Does it matter how the person got hurt as to how much sympathy you would expect to feel?

Initially, I had all the ‘oh my god’ feelings. I was very sympathetic and have been trying to help, but now, I am having a hard time with it because it was because he was riding his motorcycle (which has been a bone of contention) and also, because he was meant to be watching our son at the time, but ditched him so he could go ride. Also, it is only minor surgery on his right arm and a cast for 6 weeks. Mixed feelings of being really super pissed off at him and also feeling bad for him because he is in pain. He is making plans to go to a concert on Friday, but I have to work in the daytime and I asked him if he would look after our son, but he just gave me a look like ‘Aren’t I in enough pain?’ I figure, if he thinks he is well enough to go to a rock concert, shouldn’t he be well enough to look after his kid?
