I agree with you
The line between consent and rape gets especially murky when the girl is drunk and all information into the case is retrospective.
I'll just go with the literal meaning of rape.
Basically a rapist is someone who wants something and uses force/cunning to get it.
It's illegal in most countries in the world.
This person broke the law willingly.
It depends on what kind of person you are and your relationship with this person beforehand.
if my friend was convicted of rape his is no friend of mine.
