Dude is one of those 'shitty sage' you'd find in some weak-to-OP MC who got abandoned by hero party stories.
Where he think himself as the best and refuse to let anyone else stand above him.
So despite him wanting a peer, at the same time if one appear he can't stand not being THE top alone.
In fact that's kind what happen next.
Abel is there, casually saying stop this shit or Abel's going to murder his ass.
Guy is confused why Abel isn't trying to change the world despite all his power.
Abel don't care, leave.
