Why are people like this?

[Mindspank]

Why do people feel the need to insult you about your personal life in a game? These people seem to take pleasure in making you feel about as big as a speck of dust. They ruin the overall positive experience of the game, they make your day horrible, they make others uncomfortable, and yet they seem to thrive in games like this.

My issue, and the issue im going to use as an example, is a 16 year old boy who seems to think its funny to tease a 29 year old man about his ex wife not letting him see his children again. What on this earth would posess someone to, unprovoked, begin to rip away at someone about something so sensitive. You would think that maybe, just maybe, he would consider the possibility of consequences for his actions. While i cannot say weither or not there will be consequences in his case, there are some lines you just dont cross.
