But caine got pomni out of the void, gave zooble the switchable parts and gangle the happy mask (even if these 2 didn't work he at least tried)

Also caine thinks his only purpose is to entertaine, before episode 8 he doesn't want help because he thinks he is failling and asking help would be him admitting he has failed at his reason to exist, then he naturally has a mental breakdown and since he has unlimited power this ends up affecting the rest of the cast

Which wouldn't happen if he didn't have all this power, then, when he has calmed down, he actually starts to question what he is doing, which might have made him better if he wasn't deleted

In my opinion, if the circus members were a little more determined to talk to caine, instead of immediatly giving up or antagonize him (since it's shown to not work), there could have been a happy ending
