Interesting question. Though I do think there is inherit beauty in suicide and especially in suicide of a bullied "innocent" kid. I think it's fair media, or whoever praise this beauty, why cover it up after all, also I think it promotes action.
I hope you don't take this the wrong way, but it is a poetic act, not being able to carry the weight of live anymore, breaking down under the pressure of "evil" in modern day society, you choose to do the last final thing anyone can do on earth...
That said, tragic indeed, does it promote other kids to follow? I doubt it, it might push them a tiny bit further down the line, or over.. but I think it only is a marginal aspect of the decision.
