Here is the thing: the guy is on his THIRD life.
There is a hint in the beginning he -may- have been isekai'd, reborn as the hero, then resurrected as the dark hero.
When he was the hero, his powers were actually stunted. It's only after resurrection that he gets his original powers back.
There is no mention of this first life, at all. It might explain why he is so OP.
I WANNA SEE HIM LOOSE AT THIS POINT, even just a little. Seeing him actually loosing just a little would make his victories so much better
