I also practice martial arts and find that the prospect of striking or throwing to defend myself acceptable, but have trouble with joint locks. The idea of hurting someone with a joint lock is very disconcerting. I figure in the heat of the moment I could defend myself, but if there was a lull I'd think too much.
depending on the martial art you will just react, unfortunately stuff like karate or kung fu taught at the local mc dojo causes more harm than good, especially if the teacher said "this move can kill" or "this move will definately break a bone" or "you do it this way in class and this way on the street" (unless it's slowing down in execution, such as a heel hook), you're screwed in a real fight. stuff like muay thai, brazillian jiu-jistu, judo and boxing that practice actual real live sparring, you'll be better off with in a real fight
other than that it will be natural and reflexive reaction, you won't even know what you're doing but you will at the same time.
i personally have no quams about breaking a join in a joint lock, kinda hard to fight with your arm hanging at your side or chase you when your heel is no longer attached to your leg. tho personal fav is choking someone else, for some reason they lose the will to fight if they wake up and you're standing over them after you choked them out
