I don't see anyone else here mentioning it, so I'll do it - there's at least one philosophy, Stoicism, in which anger is a vice, basically a bad thing, to get rid of. By "get rid of" I don't mean suppress or somehow hide it, but change your worldview (internal narrative) in a way that makes it disappear. How to do that? Given that anger is the emotional expression of an opinion (narrative), that some rule that's important to you has been violated (an injustice happened), you change that narrative to weaken the assumption that the injustice mustn't/can't happen. An important thing is that it doesn't mean that you don't react to the injustice, quite the opposite--there's a whole part of Stoicism for that called "discipline of action". It's just that you act on it out of principles and not driven by emotions. Here an overview of Seneca's "On anger": https://en.wikipedia.org/wiki/De_Ira https://en.wikipedia.org/wiki/De_Ira
