Let your conscience be your guide. But Cho Seung- Hui's conscience blamed the world for his own misfortunes and hardships. Much like John 'Plato' Crawford in the Movie - Rebel Without A Cause he decided to make the world pay. And pay they did - Thirty three lives lost and many wounded.

In the movie Plato finally cracks and decides to kill his fellow students who had been bullying him in school and Cho on his part felt let down by his fellow mates at the university. 'Plato' shot two people in a mad rage but Cho was systematic in his killings, he even returned to a class room to spray bullets to ensure that the students were dead.

While watching the movie -Rebel Without A Cause I was struck by Jim Stark's cry for help where he pleads with the adults to help him curb the raging demon within himself, where he lashed out at his father and the detective when they told him that ten years hence he would see how little his current suffering mattered.

What they said was true its important for the youth to look beyond their current heartaches to the future ahead and most do manage to scrap through the tough teen years to become stable adults but the few that remain mired in their little hell holes become dangerous to others in some way or the other.

Both Cho and Plato resorted to violence. In the recent video that was part of the package Cho sent to NBC he ranted about the shit the students had bought on themselves and absolved himself of the killings:

"You had a hundred billion chances and ways to have avoided today......But you decided to spill my blood. You forced me into a corner and gave me only one option. The decision was yours. Now you have blood on your hands that will never wash off.....I didn't have to do this. I could have left. I could have fled. But now I will no longer run,"

And in both the cases the signs of mental problems had been apparent. Plato was seen acting like a moron in the Police station and Cho had been admitted to the mental hospital back in 2005 and professors and students alike had complain about his aggressive behavior.

By the end of movie it was quite apparent that its never the sane teens who take lives no matter what kind of suffering may plague them but those who are born bad, those who have lost their bearings and sense of right and wrong who indulge in carnages.
