Put one in the chamber whenever I'm feeling this anger
Putting one in the chamber is a reference to killing one’s self. If you were facing a gang of murderous cops or a zombie horde, and you only had one bullet left, would you:
A) kill one of them and face your horrendous doom, or
b) take your life in your own hands and kill yourself?
It seems that Pac has made his opinion clear in this matter.
