I honestly would love it if the MC just went full douchebag, a la Shinji Matou-style. Get rid of the moral barriers in his mind and just go around manipulating everyone who fucking walks the earth while acting smug all the time.

It's rather unfortunate that you can't properly reply to criticism, and instead can only strawman arguments. At least try to form a semblance of a response instead of redirecting your words to a different topic.
