Distrust of mankind.
What happens when a person feels
betrayed after realizing that their personal concept of morality isn't compatible with mankind, yet continues to

Misanthropes, people who
subscribe to misanthropy, are frequently people who simply feel
betrayed after realizing that their happy-sounding belief that is
incompatible with humanity.
