The Clearest Example Of Narcissism’S Dangers Is The Bernie Madoff Scandal: Madoff Showed An Utter Lack Of Empathy, A Superiority Complex, And Crafted An Elaborate Scheme That Only Benefited Himself

Narcissistic personalities care only for themselves and will do whatever it takes to feel superior.

This can be best seen in the classic tale of Cinderella, where her evil stepsisters are a great representation of narcissism.

These characters felt they were above the law and exempt from society‘s rules, illustrating how they would lie and cheat to get what they wanted.

Further evidence of this can be found in the 2001 Enron scandal, which was caused by two narcissistic CEOs – Jeff Skilling and Kenneth Lay.

These two showcased their entitlement by encouraging their 20,000 employees to invest their life savings into the company, despite knowing that it could easily result in everyone losing out financially.

Dangerous narcissistic traits also include arrogance and lack of empathy, both shown clearly by Bernie Madoff when he used money from new investors to pay off current clients whilst simultaneously believing himself to entitled to every penny received.

And unlike Walt Disney who envisioned Disneyland as a place for families to have a good time, narcissistic figures like Jim Jones instead use their grandiose schemes only for their own benefit without thinking about others.

Understanding The Risky Behaviors Of Emotionally Unstable Personalities

The emotionally unstable personality type is known to act in ways that suggest a fear of abandonment.

These individuals might frantically search for acceptance and attention, often through impulsive or reckless behaviors.

They may even use manipulation or even threats of suicide in order to gain the attention they crave.

A tragic example of this is the case of Phil Hartman, the famous Saturday Night Live comedian who was married to an emotionally unstable woman.

After he threatened to leave her if she started using drugs again, she fatally shot him before killing herself.

Similarly, Bonnie Parker from the notorious bank-robbing duo Bonnie and Clyde had signs of emotional instability, evidenced by her impulsively running away with Clyde Barrow and their string of headline-grabbing bank robberies that resulted in the deaths of nine police officers.

And Anna Nicole Smith’s impulsive sexual history led to numerous men claiming to be the father after her death from an overdose in 2007.

These are all examples of people with emotional instability who fear abandonment and thus strive for attention at any cost – even if it means harm on some level.

The Warning Signs Of Paranoia: How A Hyper-Sensitive Warning System Affects Minds, Morals, And Actions

Affects Minds

Paranoid personalities can see anyone as a threat, which sometimes leads to hatred and violence.

From neighbors to coworkers, to governments and ethnic groups – no one is off limits in the constant search for validation of irrational fears.

This tendency towards suspicion and hostility has been seen before in many famous paranoid personalities, from President Nixon’s listing of enemies to Adolf Hitler’s Mein Kampf.

Paul Jennings Hill was another example of this kind of paranoia taken too far, believing that he was justified in murdering an abortion doctor by the name of John Britton and his bodyguard James Barrett.

Unfortunately, this type of paranoia isn’t just limited to individuals – it can be seen in hate groups such as the Ku Klux Klan or Aryan Nations as well.

Members often join these organizations as they don’t need convincing that their negative views are correct and furthermore these organizations provide opportunities for members to engage in visible forms of aggression which only feed into the paranoid person’s fear-based beliefs.

The Chilling Reality Of Predatory Personalities: How Words Can Deceive And Manipulate

When it comes to dangerous personalities and their impact on society, the one pose the biggest threat is the predatory personality.

These type of people have no conscience when it comes to their actions, making them cold and remorseless in their behavior.

They will do whatever it takes to get what they want, whether that’s stealing something or using violence for sex, which can be seen in Josef Fritzl who imprisoned his daughter and was unfazed when asked about his atrocious behavior.

Henry Lee Lucas summed up this unique mindframe best when he said “Killing someone is just like walking outdoors.

If I wanted a victim, I’d just go out and get one.” Predators take advantage of people through words, manipulating them into doing what they want by exploiting emotional weaknesses even if it means taking a life away in cold blood as Dennis Rader did with 10 victims that earned him the title of BTK Killer.

Jack Henry Abbott provides an ideal example of how a predator can deceive innocent people by gaining their trust with eloquent words despite stabbing another inmate to death years before.

Norman Mailer testified on Abbott’s behalf leading to his release only 6 weeks later before he killed again showing that predators make no hesitation or remorse when they kill; they simply act on impulse leaving tragedy behind in their wake.

The Dangerous Power Of Combining Multiple Personality Types: The Case Of Joseph Stalin And Warren Jeffs

People can have multiple dangerous personalities, and this combination of characteristics has the potential to create an even greater risk of doing harm.

For example, individuals who are narcissistic and paranoid exhibit worse behavior when combined than either would on its own.

An infamous example is Joseph Stalin, the Father of Nations and Brilliant Genius of Humanity.

Not only was he a narcissist with a thirst for validation (evidenced by his many honorary titles), but he also had a paranoid side which led him to execute almost a quarter of his military staff after World War I due to suspicions that they were unfaithful.

This eventually led to an estimated 30 million people dead as a result of Stalin’s dangerous double personality.

Another example is the case sof Warren Jeffs – the leader of a polygamist cult in Utah – who was arrested in 2006 for sex crimes involving young girls in his congregation.

His egocentric nature was evident in his beliefs that God had bestowed him with authority over earthly laws, while his predatory tendencies were clear from the lack of remorse he showed toward those he abused.

Finally, Jeffs’ paranoia could be seen in his desire to keep outsiders away at all costs.

Staying Safe From Dangerous Personalities: Strategies And Advice To Keep In Mind


In order to stay safe from dangerous personalities, it’s important to be aware of your surroundings, plan ahead strategically, and carefully consider people’s intentions.

Dangerous activities occur most frequently between 8:00 p.m.

and 2:00 a.m., so if possible, plan errands or outings earlier in the day when you can remain vigilant and aware.

Additionally, when you go out to places like an ATM machine or store at night, be sure to pay close attention to your environment– predators may try to get too close in order to control you mind, body and feelings.

Remember that niceness doesn’t equate with goodness; this is an important distinction as sometimes dangerous personalities can act nice but have wicked intentions behind it.

John Wayne Gacy, a serial killer and sexual predator notorious for dressing as a clown for children while his neighbors praised him as a nice guy is one example of this mindset.

If you do determine someone poses a threat, form supportive alliances such as confiding in trusted friends or local services and set firm boundaries without giving an inch room for argument or persuasion by the dangerous personality.

With these strategies in mind, you can protect yourself from danger by staying aware, strategic and understanding of people’s intent .

Wrap Up

The main takeaway from the book ‘Dangerous Personalities’ is that we all need to be more vigilant when it comes to recognizing potentially dangerous individuals.

We need to be able to identify the signs that dangerous personalities may give off, and take the necessary steps to minimize any risk they may pose.

Questions such as: do they negatively affect your emotions? Do they act erratically or unethically? Are they manipulating or exploiting you? Are they often engaging in dangerous behaviour? And are they impulsive and out of control? Can help determine if someone poses a threat.

By being aware of our surroundings, and knowing what to look for, we can make sure these potentially dangerous people don’t get too close.
