All that is necessary for evil to prevail is for good people to do nothing.

Others are not born bad or good... and neither are people, by the way.

Anytime there's a God, there has to be a devil. And anytime there's good, there has to be evil. And the evil sometimes is the best!

People's character is their behaviour - we're all capable of good and evil.

What's the use of being good if you are not good to yourself?

Good at the wrong place and time becomes evil; evil in the right place and time becomes good.
