Report Is revenge bad? in Questions about Objectivism Posted March 7, 2012 Is there a meaningful difference between revenge and retaliation? Just by connotation I would say retaliation can be delegated, but revenge is something more personal. Either way, in an extreme case like what you're talking about it would be moral to take revenge, with the full knowledge that unless you uncovered new evidence in the process it would also be moral for the police to arrest and prosecute you afterwards. Waiting for the worst of the anger to pass, assisting with the investigation and exhausting other options are still higher on the list of actions to take after being victimized.
