>>10208659You wanna meme answer or serious answer?
Meme answer is fuck his brains us for tempting his brother to do this kind of shit.
Serious one is listen what he has to say first, try to look things at his own perspective, and you may pick up "wait a minute that's not fine" stuff.
And there is "thing from the birth", not much you can do about that besides supporting him.
Regarding the "wait a minute that's not fine" stuff, that may have caused by some kinda traumatic event that happened during childhood(possible rape/abuse etc.), influence from media or friends, etc.
