Hahaha, lol, but many found this an interesting and respectable twist at least on a typical and familiar formula.
By the way, in his other film, Abel Ferrara's "Ms. 45" (aka "Angel of Vengeance") (1981), the woman, played by the late actress Zoe "Tamerlis" Lund, who also co-scripted this film and had a small part in it, not only killed at least one of the men who also violated her but she went even further than that, taking on the male gender in general and started seeing almost all men as evil scum.
His (Harvey Keitel's) character also at one point commits an offensive act of a sexual nature/verbal abuse himself in this film, which sort of says he isn't all that much better than those two young men who violated that nun in this movie.
True. But doesn't he evolve by the end? He does terrible things through most of the movie, hence the title. If he can forgive the rapists and put them on a bus to somewhere else, can the audience forgive him for what he's done up to that point?
