Completely agreeing with you about the whole respecting people's graves and stuff (and I know this is just fiction) I think the brother and the guy just had one of thos moments were you just do somthing first then think about the consequences later-(meaning I think the brother would hate himself after doing it on his sisters grave).
Hmm I know it's just fiction and stuff, and I know you can see it in different ways, but seeing the brother and the other guy forgetting about shouko so fast, and doing such a disgraceful act at her grave just made me feel really bad. I think you should treat a grave with respect (and not rub your dick against someone's grave stone) and they could have prayed normally to shouko and just go to a hotel...
