There is a huge difference between being aggressive and being assertive. You can be assertive, express your hurt feelings and ‘vent’ without resorting to hurtful comments.
If you know your verbal retaliation knows no bounds, then do something about it, unless you want to isolate yourself.
Also, anger is nothing more than an emotion. I find it very frustrating when people blame their actions or behaviour on ‘anger’. It implies that this is something that simply cannot be controlled. Everybody in the planet experiences anger. The difference is in how we manage this emotion.
