Should fighting be banned in hockey?

Hockey is the only major professional team sport that condones fighting. But is the violence necessary or is it primarily for fan entertainment? Recent off-ice deaths of NHL enforcers and the post-death discoveries of their physical and mental states have turned the spotlight on fighting and the impact of head injuries. Minor hockey leagues don’t allow fighting and now junior hockey leagues are considering bans. Can the NHL be far behind? How would paying fans react? Will hockey hold the same place in Canadians’ hearts if fighting is no longer a part of the game?
