Could someone use marijuana for a way to cope with their sociopathic tendencies, or unempathetic mindset?

When my boyfriend would smoke he is wicked tolerable, kind and generous. Since he is planning to go to the military he is slowly trying to quit it. He becomes very irritable and intolerable at times. Manipulates any discussion with me to make himself seem more egotistical and logical than what I have been trying to say. He would lay down the line and harasses me on every move or topic I would try to discuss about. It is almost impossible and blames everyone else.
He thinks he is always right. People are pests to him that he thinks should be controlled or there is no order in the world. He has a fascist mind when he talks about what he would do if he is in power and looks up to the ideology of cults in the means of people following his order to have peace and love by fear of brutal torment, manipulation and orgies if he was to rule. He believes that he is the most intelligent and he gives no care to anyone because of his abusive childhood. We both Uber. I simply wanted to tell him a story of a man who told me of his daughter brutally injured in the Navy and was about to be taken off life support. My boyfriend twisted the story saying I told him this to get him to change his mind about going to the Marines. That my story had no full facts and that it was either my intention of swaying his move to go to the military or the man's move to make a move on me. Nothing I said, made him believe me. I got frustrated and my boyfriend showed no empathy to anything.
My boyfriend told me a story of a woman earlier same day of a woman he picked up from the hospital having terminal cancer and she mentioned how his name is of an angel. Contemplating on the phone with me if he was actually an incarnated angel. But my experience was incomplicent. It became a huge heated discussion, arguments and silence.
This was just the second time he would come after me and point to me all my flaws throughout the day. Does marijuana help certain people like this? Does everyone get so irritable?
