So, in conclusion, MC is complete and utter shite with no redeeming qualities, and his harem is confirmed to love and cherish him unconditionally despite that, leaving him absolutely no reason to ever try to improve upon himself or become a better person. Also, he's the best among the humans? The author must have an extremely dark perspective on life and society if the MC is the best kind of person they can imagine. It's like, most isekai are wish fulfilment fantasies, but in this one the sad reality that generated it shines through more clearly than usual.
