Yes, 30 years ago. So, what? He took a life and is now a millionaire NHL luminary. That's the point. You're mixing apples and oranges.
I don't really know the facts of this case. The guy might have done it or he might not have. He pled "no contest"; he wasn't convicted on the felony charges. If the HF Boards and the LA prosecutors were so certain he was guilty, one has to wonder why they offered a plea deal. Whatever.
Didn't demigod Lucic slap around his girlfriend clubbing one night a few years back? Don't recall anyone calling for his immediate trade, or banishment from the league, back then.
Guess the answer to the question depends, as it always does, on whose ox is gored.
