One can have sympathy for the dead CEO's family or his relatives. They didnt do plan UHC's controversial, hated insurance policies and premiums or have any role in their implementation. I can feel sorry for the shooter's family, too because now while he has a large amount of public sympathy who "understand, but don't support" his actions he won't be seeing his kids grow up while he's in prison and most times he'll see them, it will be in the visitors waiting room in whatever federal/state penitentiary they put him in to serve his life sentence.
It's not like health insurance CEO's are the only morally-bankrupt, greedy, selfish people who work in our whole economic apparatus sector. Down the road from where he was shot and killed, you have selfish, greedy and morally deficient stock traders, bondsmen, hedge fund managers, the CEO's of massive multi-national trading corporations, energy groups that have unlimited access and power to influential politicians, parties that rival, if not exceed what was available to this guy.
Where does it end?
