I don’t have to defend anyone against murder, it’s illegal and wrong.

Usually illegal, not always wrong.

I would prefer to see a distasteful person sent to retire to rural North Dakota, rather than murdered, but maybe I’m a little soft.

Do you think UHC is bad because the CEO happens to be a uniquely evil person and if it was someone with a good heart it would be good?

What kind of alternate reality would that be? The people heading these companies are good at rationalizing why they are not evil. Don't play their game.

The interesting question to me is where murder is justified in your ethics. You came in with absolutes, after defending him.
