I missed that he'd only killed half of them. But since more than half of them died in Hela's attack, I'd think killing any of them at all doesn't conform to his "principles." He's so clearly irrational and unhinged while thinking he's the only sane one.

Yeah, the Sharon/Steve went over with a thud. I didn't hate it on principle, but I didn't like the way it was executed.

I agree that Natasha and Steve have tons of chemistry. Tons.
