The trouble with cutting is there seems to be a sort of stigma about it, in reality it's no different than punching a wall and way better than drug addiction or alcholism. As with alot of destructive behavior there will be people who do it for attention, but to call these people pricks is a pretty stupid thing to do, there are as many valid and understandable reasons for seeking attention as there is for self harming.
There are many reasons why people may act in a certain way, wether their actions are due to past events or recent events.
Don't judge people without knowing their circumstances, im pretty confident everyone has ways of dealing with things, or have done things that idiots could easily judge just as harshly, but im sure the large majority have understandable reasons behind them.
Anyone who manages to get better and deal with issues that are crushing them should be respected.
I was put into foster care when i was younger, it wasn't great but it didn't effect me badly, yet i know people who were in similar situations and had a very hard time getting over it. There are things that i found extremly difficult to get over yet these same people got over with minimal hassle, am i stronger than them? are they stronger than me? I don't think so, i just think people are different.~
Of course everythings circumstantial and i do belive there are some things that really have justifiable reason behind them.
