There is a difference in you compared with them
Based on what I know of the Finnish incidents (which is not much, I admit) there is a pointed difference in you compared with them: you’re very much aware of all this and of the consequences it might or may at some point have, and despite being ignored by (IRL?) people you’re still making it known not only in circles that only approve of and encourage those disastrous consequences. I’m not sure of your age, but your awereness could be due to the fact that you’ve not had the opportunity to act your fantazies out as early as Saari and Auvinen did, which has given you time to work things out more. So you have no need for a half-assed übermensch philosophy to support how you feel; instead you know you’re a murderer in the making, produced by the society and by the evil of your juvenile peers.
(Not sure if I had a point in there somewhere. Just stream of consciousness I guess, thoughts brought on by what you wrote.)
