Stan: “You are simply bad product”, no respect there.

Soldier Boy would just think Homelander is being some sort of annoying boy scout if Homelander was genuinely trying to be ethical/good/whatever, there would be no respect there.

Butcher would maybe respect Homelander but he certainly won’t like him, he just doesn’t like Supes. Also I’d assume that all the other Supes are still doing their own thing so Butcher would still dislike them all generally speaking. e.g. A-Train would still end up killing Hughie’s girlfriend, Deep would still be a POS, Supes would still be responsible for all sorts of collateral damage, etc.
