Most of us assume that people are trying to be fair and honest. We never even consider if that new friend we just met is a decent and moral human being because most of us belief in the inherent goodness of man. However, there are individuals so different from the rest of the population that they may even represent a subspecies of humanity. These people behave most of the time like any normal human being. With one major exception, genuine and sincere feelings toward others are completely absent. Almost certainly, no one would stop and think if someone has a conscience or not, we trust every person around us is like everyone else. However, to have a conscience is more important than intelligence, race, or gender- and that is what differentiates these people from the rest of us- the terrible bareness in their psyche. Whether they are a corporate raider, bloodthirsty tyrant, ruthless social predator, a serial killer, or a lovely, innocent- looking social butterfly, these individuals have no conscience at all. In other words, they lack emotions, like love, kindness, compassion, remorse, and pity. Nevertheless, they pretend and impersonate those feelings, but theirs are superficial and false.
