First of all, CEOs of giant corporations and companies are rarely involved in day to day operations and information is usually filtered by the time it reaches them but here's a "What if?" for ya- what if he actually wanted to change the way United Healthcare operated? Everyone is assuming he was a complete A-hole greedy MFer and wanted nothing more than to see people suffer but what if he was actually a decent person? Mangione and everyone else seems to be assuming that was the case.
I doubt Thompson's family is thinking "He was a great husband and father, but he sure was a POS at the office".
It doesn't matter what he did in his professional life, it's NOT OK to sneak up and shoot him in the back, or anywhere else. The fact that Mangione didn't have the balls to face Thompson says a lot about Mangione- chicken poop. Shkreli or the Sackler family- I might give someone a pass for them. Putin, definitely but his replacement needs to be vetted before.
