It sounds to me like the anger is a symptom of a larger problem. Is it possible that he could be bi-polar or have a personality disorder? This is no small thing that you should overlook. I would not marry him unless you are willing to cope with whatever his problem is for the rest of your life. When you add the responsibilities of marriage and children to the mix the problem will only get worse. You said something about his mother in one of your posts. Is she abusive? Does he have any kind of a relationship with her? Whatever his family life was like, he is likely to duplicate it as it is the only way he knows for a family to be. I married into a highly dysfunctional family and I have paid a very high price for 20+ years. My husband has been verbally and emotionally abusive while at the same time telling me how much he loves me. It is very confusing and difficult to figure out. I would not wish the pain I have felt on anyone. After 28 years of marriage I have finally deiced to get out. It was not an easy decision and not at all the plan that I had for my life. Looking as far back now as when we were dating, I can now see the pattern. Being only 19 when I married I thought love conquered all. It doesn't. My advice would be to examine your relationship very carefully, don't ignore the signs and if you don't like what you see get out now before you subject yourself to a lifetime of hurt and heartache. One good book to read now- The Verbally Abusive Relationship by Patricia Evans. It will at least help you to see what's going on in your relationship and then you can better decide what to do.
Good luck! Don't settle for second best.
