Hunter said something about just wanting every girl. The only reason he stopped was because he actually fell in love with his wife and for the first time, wanted to be faithful to one woman. It was after his wifes death that he returned to his old ways and every girl was game. he just wanted to wait until Ophelia was 18 to make his move, but David got her pregnant first.
Long story short, he fucks just to fuck.

True, but he also mentioned that he's about to die soon to Drew even without getting half his body replaced, and a dying man usually wants to do four things:
Get his business in order.
Make peace with his mistakes.
Find himself a legacy to carry on his deeds.
And go absolutely fucking buckwild.
And you know, in a way, what he's doing in the game is just that from his point of view. He's trying to settle his great wealth and deliver it to his family, he's trying to mend the bridge he burned with his family, he's trying to find himself an heir in Sterling at first, and he's having fun in the last moments of his life doing what he loves doing.
The fact he's psychologically reliving fucking his dead wife by fucking every single other member of his family that was related to her is also an added bonus, one he's using to justify his monstrosity. He's doing it for love. He's doing it for her. He's doing it for them.
Or at least that's what he makes Drew Believe, to get her on his side, the bleeding heart she is, who has an idealised view of what they do, one of chivalry and friendly sport. Who knows if he's even lying about his failing health leading to him wanting to fuck the family...
After all... Hunter seems to be in perfect health and perfectly happy in most far future bad endings... And is perfectly willing to wait the long game to fuck with Starling's mind in the most recent one, 18 months after the current summer too.
