What happens when good people are put into an evil place? Do they triumph or does the situation dominate their past history and morality?

I have been primarily interested in how and why ordinary people do unusual things, things that seem alien to their natures. Why do good people sometimes act evil? Why do smart people sometimes do dumb or irrational things?

The line between good and evil is permeable and almost anyone can be induced to cross it when pressured by situational forces.

No matter how hard Evil tries, it can never quite match up to the power of Good, because Evil is ultimately self-destructive. Evil may set out to corrupt others, but in the process corrupts itself.

Religion has a good place and it has its good people.

You know how confusing the whole good-evil concept is for me.
