Society Knows Evil

"What does, or ought to, separate us then is our highly developed sense of morality, a primal understanding of good and bad, of right and wrong, of what it means to suffer not only our own pain—something anything with a rudimentary nervous system can do—but also the pain of others. That quality is the distilled essence of what it means to be human. Why it's an essence that so often spoils, no one can say. " -Time Magizine
If humans develop a sense of right from wrong then why is evil still attractive? Throughout time humans deals with moral decision or good and bad. Somehow although the right thing is drilled into people's mind evil overcomes and ultimately wins. Evil things are usually wrong and immoral but still attractive for some reason. Maybe is the urge to rebel or try something new but why do people choose evil when they clearly know its wrong. Is it really human nature to be evil, are we naturally good or evil? Are there good people and evil people and theres no changing who you are? Evilness overtake a person and is hard to break free from but why are humans constantly attracted to evil?
