A wise man once said, that fighting for peace is like #$&*@! for virginity. But anyway...In my oppinion, bringing death, if not done by Death itself, is evil.
Accuser, Executor, and Tyrant are not all bad aswell, on the other hand. Accusing someone is not bad if justified. Executing(orders) is alright, if the orders themselves aren't evil, and Tyranny wasn't such a bad form of government, back in the ancient greece. We're going in circles...What kind of action or deed is actually evil for you?
And mind it...If u're bringing death to the intolerance of other ideas, how is your idea ever proven wrong? U leave people no alternative but to overcome your death threat, and prove you wrong by force. If you have an idea, you have to be prepared to take some criticism, not to just kill anyone who oppose it...And let me tell you, a sith lord with means of mass destruction in his hands, doesnt admit wrongs likely.
