Well there was no OFFICIAL proof that they were homosexual, although there are many arrows that point that they were, besides that they killed alot of people for money in order to survive..so it'd be up to the person.
But moreover there isn't such a thing as Heaven or hell in Naruto, it's never been shown or talked about in a serious way.
i think that they both went to heaven but that's just my opinion i think that they were good in the end only but they could have gone to hell for killing but hey u never know where they went heaven or hell
