Is it wrong to satisfy this urge?

Alot of people release anger this way. Others go off the wall and purposely look and engage fights with people in real life. Which is worse to you? As long as you distinguish that you can do it in a game, but that it is wrong to do it in real life youll be fine. Note that people watching you do this can and or will assume that you mowing down people on a game can be stepping stones to aggressive behavior in real life.
