I do not think violence is irrational as a remedy to certain situations. However, opting to settle issues with violence is less rational than using other means because it does more harm and less good. There are people for whom the only choice is to use force,, even if not violence and there are times when non-violent practices lead to personal annihilation. However you are talking in such instances about situations that are already deeply involved with degrees of insanity.

Violence is almost always less rational than other means of control or persuasion. That doesn't mean it's always avoidable, eh?
