What are the chances of a teenage boy like this turning into an abuser?

I’ve been thinking of some very unpleasant dates I had back in the day that were mildly abusive. On one , we were sitting in his car at age eighteen and he yelled, “shut up!” at me. I think I have now gotten rid of him on Memory Lane. Then with another guy who married my best friend: we were at the beach and there was a deep hole. I was already nervous then, at sixteen, dating such a good looking guy. He shoved me down the hole and I was in just a bathing suit and so embarrassed. In sixth grade, a boy, now deceased, came to our door and when I answered he slapped me hard across the face. He actually became quite popular. I was wondering lately what the chances are that those guys are now abusing their s/o’s? What is your opinion? Just ‘guy stuff’ or budding abusers? I know for a fact that there are so many men who appear to be very sweet but people just don’t know the truth.
