You look upon the face of true evil, you ain’t liable to forget.
Without good, there is no evil.
Who’s more evil, Doctor, the taskmaster or the tasked?
When you consider the pain that you cause a person the person’s fault… that’s evil.[to Jamie]
We know we can’t defeat evil. All we can do is point it in the right direction.
No one ever thinks that they’re the evil one.
If you support evil, you are evil.
I’ve made my choice. It may be wicked, it may mean I go to a fiery and horrible place when I die, but it’s too late to stop now. I will not stop. I’m going to win or die confronting the Master. I will not fade away as a weak old man.
I believe in evil.
Evil won’t die on its own. It only festers.
Evil triumphs only when good men do nothing.
Evil people aren’t the exception to the rule. They are the rule.
