Walt ain't do shyt to earn respect. He destroyed everything and is making an uneducated attempt to fix their fukk-up like a 9 year old. Only difference is that he is so full of ego that he actually thinks he can do it better. We're starting to see how wrong Walt is.
There was no benefit to shooting Mike. There were no loose ends...Mike had his money, had his way out...he was gonna disappear. Now he's dead and Walt's gonna have to dispose of the body without anyone knowing (except maybe Todd). No half measures doesn't apply here
