Hell Benny was just after revenge, he's barely better. Like you can straight up walk away after you kill Hart on his route, because he doesn't care about five really, he just wanted to spend time with his friends. But up until the end of the game he was willing to be complicit in what they were planning to do to five.

If Hart hadn't slaughtered them in the rod route they were gonna do the same thing the Lovelies would've done, maybe slightly more humanly, but then again there no humane way to rape someone now is there.

And like I said Liam and Clyde were willing to rape five, yeah maybe it was out of a sense of "for the greater good" instead of straight up hedonism and sadism. But it should be Five's choice, would they have done the same if they found Buddy?
