So Pennywise could've been a victim of it?? We know "It" is able to control people and present it to others (as we see with Patrick and Henry) so Pennywise could've been a normal person who fell victim to It??
It’s likely that during one of IT’s cycles a circus came to town with Robert Gray (aka the real pennywise) and saw him scare some kids unintentionally but he didn’t have to be a victim of it (even though I imagine him being that and killed him disguised as him)
