I honestly say no, he isn't even arguably the hardest boss despite being infinitely stronger, he attempted to destroy the multiverse /reality to rebuild it but that's rather common. Even then its just shown as floating platforms which I always just took as not having destroyed anything yet just as symbolism of realities with it not even stated he succeeded with killing anyone and before he gains the godhood he did little other than rather small terrorizing in cutscenes and threaten a person which honestly he could of been shown doing a lot worse in my opinion. Hell Carnage who had less resources might of been feral but had a far larger body count from what I recall.
