From an evolutionary standpoint, getting raped is nowhere near as bad as being an incel
Human behaviour has evolved through billions of years to maximise the survival of their genes. That is why they are so protective of their offspring and why they love their relatives.
So let's look at rape vs being an incel. If a woman gets raped, he risks having his kids carry genes from a genetically perhaps not as fit male. He also will not get the father to offer resources for them.
Compare this to life-long inceldom, which kills your entire descent. It's not even remotely close. Being an incel is something far worse than getting raped and therefore being an incel also means much greater psychological stress and pain.
