some one kill 9 people

i heard on the news that a 23 year old student in FINLAND, open fire into school,killing 9 people and hurting a lot more. Before the shooting, he upload his photos of shooting on U tube,
I don't understand why people have to do things like this, what i think is that he wants attention.
i think wanting attention is the worst thing , it can destroy people .That is why people are doing a lot of foolish things just to get attention.
may be i am wrong, but in the past, people know each other, what ever happen, the whole village will know about it,
but in this world,no body know anyone any more, may be that is why there are a lot of suicide.
just to be talked about.
