Sort of? The bad endings all have rape and violence since Aoba, the protagonist, destroys their minds. Most of the characters aren't "rapey" by nature, though, Aoba's powers are what cause them to go nuts. This one isn't actually even an Allmate, he's a fractured piece of Aoba's own personality that got implanted in the robot body or something, but digitally/psychologically projects as the bishie. I think in his bad ending he just eats Aoba, honestly can't remember if there was rape as well.
