Evil Characters - don't care whats right right is for the morally good people, they want to be bad.
See i think that's the core of our disagreement here.
No one 'wants' to be bad.. But everyone wants to be happy.
People have dreams and goals and needs that have to be met (be it something simple as hunger or more complex as emotional need and such). All this to ensure happiness.
The difference is that 'evil' and 'good' peeps handle it differently. A person who will put themselves and their happiness above the rest ends up being 'evil', a person who won't ends up being 'good'.
Will i sacrifice everybody if it means that i can remove the tadpole and live happily ever after, or will..not do that, lol.
Now obviouslly this is all very black and white, very simplified.. but you get the idea.
