At the end, SPOILERS ALERT, why did that...

... young fella in the fourth segment kill himself?

And also, not meaning to be too controversial, or laden in heavy discussions on anything here, but I was kinda wondering...

Was it implied that the reason he killed himself was because he was humiliated when that girl tried to [spoiler]inappropriately touch him[/spoiler], did he feel this bad about it so he decided to take his own life?

Or was there something else that led to him doing it?

Thanks.
