Agreed he got the sentence he owed to society, He never complained about it. Vigilantism always turns bad if a blind eye is turned towards it. But the reality is, he is no threat to society beyond the fact that he will protect his family and he displayed rational thought to the judge that if he had been older and wiser he would have defended himself and his wife then and there. Which is not vigilantism it is self defense. Do I think he is still capable of the same act, sure, but I think the event is highly unlikely to happen twice as they are both more mature and take security seriously, and well lets face it she is not in her early 20's anymore.
