This makes me wonder a lot.
Some users here have been on HF before and been really fed up with those spoiled kids and retarded people but what is really going on in their head?
I mean what are they seeking with those kind of actions?
Do they want to break the world just to prove that they exist?
Do they feel like it gives them pleasure to do those kind of nasty stuffs to others?
Do they think that it's really a mean of getting money?
Do they really think they are 'l33t haxor' and that it makes them learn awesome things about computing?
Do they believe that beeing a 'bad' guy is cool?

... lots of questions comes to my mind.
However, are those useless things really worth wasting time?

I've been doing all those 'bad' stuff before but I ,at least, got over it in a good manner.
The transition was done when I was doing more coding then vandalism; I mean I coded automation to do the vandalism for me which lead to me beeing bored by those things.
Boredom removed the excitement I had for the stupid stuff and transformed it into excitement for creating things.

Moral : creating is way more enjoyable then destroying.
Destroying helps you learn the value of creation.
