I'll admit to misanthropy, to a degree. I think mine was born as a result of trauma i suffered as a boy. I was sexually violated by a family member for almost 7 yrs before i had the courage to speak out. The result? My parents accused me of being a sinner and the authorities didn't believe me. I was shamed. As a result, i tended to assume the worse about people; i'd refuse to give them the benefit of the doubt. It only got worse as i aged, horrible world events, daily news of some unspeakable horror commited by someone; it all convinced me that humanity was without hope. The realization of this only made me miserable, and by extension, everyone else around me. I lost friends. People avoided me. Understandable, in hindsight. Eventually i realized that my hatred of people was only hurting me; no one else. Furthermore, it wasn't constructive. So to answer your question, yes, misanthropy is justified, but i can tell you from experience that it leads nowhere. Nowhere but a state of constant grief, hopelessness, and disappointment. You'd be better served directing the sizable amount of energy you waste hating people into doing something to break the mold. Even if it's only something minor, like helping someone with their groceries, or volunteering at a soup kitchen. That helped me.
