In the game I'm developing I've written a bit in the to-be-released rulebook on playing evil characters:
"Whether you are good or evil, lawful or chaotic is determined by your own actions. This means you are free to play an 'evil' character just as you are free to play a 'good' character, as long as your plot committee hasn't stated otherwise. Just be aware that if you decide to play an 'evil' character that the plot committee is under no obligation to protect your character from their personal blunders. If your character is able to pull off all kinds of evil acts without getting caught, you are playing evil correctly. Just remember that if you want to play 'evil' and not suffer retribution for your actions from your fellow player's characters or non-player characters, you must play smart as well."
