Or rather, why do some men rape?
This has always been something that bugged me.

I've just told been told that men rape because young boys view rape as less of an immoral crime compared to others, which is news to me because I've always seen rape as one of the worst crimes a person can commit, and because of the way we're socialised. Such as the way we use language involving rape (I'd assume that'd be due to victim-blaming) and media we consume.
So, I thought I'd ask the only place I know I'd get a proper answer. So, why do men rape? Is the person who told me the previous reasons right, or are they misrepresenting facts (to spout a misandric point)?
Edit: Not implying all men are rapists, or men are naturally inclined towards rape. That's all bullshit. I've just heard someone else's argument that claimed men rape because men don't think rape is bad, so am now just asking for ammunition to show why that point is stupid.
