Perhaps he felt guilty about hurting those around them? Or maybe this was his way of resolving things?

Or it was just an accident?

No it was definitely not an accident if you review the whole thing closely and I would say it was his way to resolve things as well. His overwhelming quilt and sadness was so great he just wanted an escape because he understood that what he was doing was wrong and he was weak by not trying to overcome it. I know that because I have found myself in that situation where I think it's just better to die then deal with it. I guess it's like believing dieting solves it and prevents you from thinking about it and gives you calmness. I sympothize with him, but he wasn't that weak because it takes courage to commit suicide,......something I don't have., but because I sympothized with him I just wished he'd overcome it and be happy.......that is just my thoughts so please forgive me if I have offended you or seem egoistic or selfish.

oh no, not in any way have u offended me there could be many scenarios and speculations (▰˘◡˘▰) I see what u mean lol I have many ideas of why it may have happened as well plus there's no concrete yes or no to who's idea is wrong or right.
Idiot!!!!!!!!!idiot!!!!!!!!!!idiot!!!!why? Why'd ya commit suicide?stupid if you loved him why did you leave him alone and make him miserable and make yourself unhappy??!!!!. Ugh I spent the entire ending crying and crying and crying even more. ヽ(`Д´)ノ
