How do you deal with aggressive people, and did I deal with my experience the right way?

I play cards with a bunch of people at uni. Since we were split up in classes, in semester, pretty much never see each other, I met some new people to play with. The problem is that one of the people is incredibly smug and very aggressive all the time when winning, or just playing normally.

He said his reason for it was that he takes his anger out in games so that he won't be angry in real life. But his friends claim that he is still angry.

I've played a few games with these people, and I've just been getting tired of having to deal with this unfounded anger. If you make one mistake in the ruling, he'll call you out on it and talk down to you.

Today, I had had enough. After having dealt with two games of this guy, I said to him that he was just way too aggressive.

He said he wasn't, and was defended by one of the guys who had started playing with them last week.

I said to him that if he couldn't see his own behaviour, that there was no way that I, or anyone else, could make him see.

Should I have ignored it? I think now that I have addressed the problem, I no longer need to say anything.
