We all have a dark side. Embrace it, but don't let it define you.
It takes darkness to be aware of the light.

You either die a hero or you live long enough to see yourself become the villain.
The line between good and evil is permeable and almost anyone can be induced to cross it when pressured by situational forces.
Sometimes, being a baddie is the only way to get things done.
Every villain is the hero of their own story.
The only thing necessary for the triumph of evil is for good men to do nothing.
We are all born mad. Some remain so.
In the end, we will remember not the words of our enemies, but the silence of our friends.

Baddies may not always win, but they sure know how to make life interesting.
Being bad is easy. It's being good that's hard.
I'm not a baddie; I'm just misunderstood.
Behind every successful baddie, there is a lot of unsuccessful goodie.
There is no good without evil, but evil must not be allowed to flourish.
I'd rather be a baddie than a fake goodie.
I'm not a baddie; I'm just creatively misunderstood.
I'm the villain in my own story.
One man's villain is another man's hero.
Evil is a point of view. God kills indiscriminately and so shall we. For no creatures under God are as we are, none so like him as ourselves.

Being bad feels pretty good, huh?
