You know, unlike some of the readers here, I'm normally fine with a "save the villains" approach. There is a lot to be said for trying to uphold justice without extrajudicial violence, etc, etc...
But going so far for it with no explanation (like, at least acknowledge it??) right after a left-hand-turn into an attempted rape scene from the villains feels like... I don't know. It's just feels like bad form. It ends up coming off like the author's implying "hey, it was just a little rape, no biggie, right? Boys will be boys!"
Like. I'm not saying you can't have a protagonist like this. You can. Written differently, they can even be compelling. But you need to at least stop and explain shit about what principles he holds so dear that he's going to risk his life for a bunch of rapists that just tried to kill him. Simply glossing over that and moving on is... at best, authorial malpractice.
