DragonLancer said:But what he has done is perform an evil act in order to combat the spread of evil, which is not a good act, nor is it something that a paladin should ever consider.
For a paladin you can't fight evil with evil and still retain your paladinhood.
But it's a logical extension of a GOOD act.
Of course, Paladins are ultimately forces for evil. Their intolerance and violence ultimately act to alienate anyone who doesn't adhere to their narrow-minded "ideals"--no matter how far from evil those people originally were. Furthermore, their unwillingness to let more rational means prevail ensures that violence constantly stalks the countryside, that revenge is always hot in everyone's mind, that violence is seen as the first recourse to any difficulty, not the last.
