Does possessing the potential and harboring thoughts that can be interpreted as evil make you evil? No. Evil is a stupid concept, and nothing in life is ever as clear cut as "Good" or "Evil." And besides, all people possess the potential to do terrible things. Am i evil for knowing that i can very easily buy a gun and a shitload of ammo, set up a sniper nest and kill dozens of people before the cops show up to try and take me down? Of course not!
I'm evil because i value the lives of dogs over the lives of humans. HA! Kidding. That doesn't make me evil either.
