Isn't Waifu Academy right up that alley? Even if you pick the "Good karma" route you're still forcing girls left and right.
The plot IIRC is some guy who seeks revenge on women for being picked on as a kid, that's pretty villainy stuff if you ask me.
Eh, I think he's a bit more justified than that. The reason is the fact that 3 of the students who attended the school that he now attends and calls Waifu Academy (I can't recall it's actual name) accused his father of sexual assault/rape/misonduct, and though the allegations were proven false in court, his reputation was forever ruined, causing the father to jump off the roof. This was when the MC was 2. The result was his mother leaving, hence his desire for vengeance against her, and him being forced to live with his grandmother and vegetable father until is father's death. He lived in squalor much of his life, caring for his ailing father, and gaining a desire for vengeance against those responsible.
That said, he's still a villain. His methods are certainly not heroic or righteous, and his vengeance can sometimes get out of hand, especially when it comes to the little reporter girl. But, his targets are mostly just in a way. Little reporter girl's father is responsible for tarnishing his father's reputation, dragging his name through the mud. The other known targets, his mother, the headmaster, the mob chick who betrayed the yakuza family and seems to be working for the rich family instead, and I suspect the third accuser is the older sister of the shrimpy geek who likes the reporter girl. I could be wrong, she might be too young, but there was a thrown away line about how hard it is for her to go back there, implying something went down there that she's ashamed of.
The way the game is developing though, while I still call you a villain, it's likely going to be an anti-villain route, something like you're the lesser of many evils and are able to save the town from the larger evils as a part of your own evil quest.
