The reason i dont feel bad for mike is because he made those choices. I understand protecting your family but he could have easily named tessio or clemenza as boss and gotten his immediate family out of the life. Mike deserved everything he got in the end
If Michael left everything to those guys, then Michael would have absolute no power what so ever. Keep in mind Michael & Vito orchestrated the massacre so there will always be people out there hunting him. Once they find out he gave up evrything, Michael would be killed immediately.
