Clearly you don't know the members on Narutobase.
Besides is it our fault he did it? I know it's still wrong and disrespectful to the dead (And no I'm not saying he deserved it) but what he did, is what he did.
It's common sense that he would know a lot of people would make fun of him for doing such a reckless and idiotic thing. Also his parents weren't doing there job, and that is making sure what's going on in his life and if anything is wrong.
His Dad even said 'I always told him he spent too much time watching the TV - he didn't know what was reality and what was fiction anymore' but obviously he didn't try making him stop, since he killed himself. He should have taken precaution and made him quit at least for a year if things were that serious, it doesn't say if he had a psychologist, but if he did that must have been a pretty bad one.
His parents should have canceled the wifi/internet and taken all his consoles. If he watched any Anime on T.V block the channel. If my parent's found out I was losing sanity like this guy, they would send me to military school.
But at the end of the day the only things you can really say is
1. R.I.P Kid
2. This guy is so stupid
