I never play a villain that I don't have something I can either do or say so the audience sees there is something redeemable about them. In other words, I don't want to do evil for evil's sake. I don't want to do Jason slasher movies. There's no point in that. ↗
Evil exists to glorify the good. Evil is negative good. It is a relative term. Evil can be transmuted into good. What is evil to one at one time, becomes good at another time to somebody else. ↗
