Tennessee Williams said this quote

I don't believe in original sin. I don't believe in guilt. I don't believe in villains or heroes - only right or wrong ways that individuals have taken, not by choice but by necessity or by certain still-uncomprehended influences in themselves, their circumstances, and their antecedents. This is so simple I'm ashamed to say it, but I'm sure it's true. In fact, I would bet my life on it! And that's why I don't understand why our propaganda machines are always trying to teach us, to persuade us, to hate and fear other people on the same little world that we live in.
