Being angry about the right things and in the right way is virtuous. But avoiding anger at all times may be a sign of weakness. St. Thomas Aquinas notes how it is a vice not get angry over things one should. He calls it "unreasonable patience." A failure to correct the wicked encourages them to persist in their evil deeds, since there are no reprimands for their wrong actions. It also causes confusion in the community over what is truly right and wrong, and thus may lead even good people to do evil.
