Why do I condone the columbine massacre?

I think what they did wasn't that bad, they got revenge in a way they could handle. I believe that no one is innocent, we all do bad things, some more than others but still. I don't believe that those kids specifically deserved to die, but I think the ones that chose to mess with the wrong people did. Sometimes I wish those propane bombs did go off, because then people would learn to not mess with people for no reason or they die. What is wrong with me!!! Am I insane!!!! I'm actually wanting children to die!!! These thoughts are very disturbing but I can't stop them, what should I do!!!?
