I don’t think you understand what that term means. People see homelander as a hero, but he’s a monster. People see joe as some kind of nice guy, but he’s a creep. Same way Dexter is a friendly and kind person, but in reality he’s a serial killer who can’t feel emotions. Haven’t watched Barry so can’t comment on him.
"Wolves in sheep clothing" bro, wherever homelander goes he does not even bother trying to hide his weird ass tantrums, it's not a sheep clothing just because people ignore the fact he murders left and right
