But why a person without understanding of emotions would troll at all? While I don't understand emotions too well and I'm a rather cold, restrained person, my actions are driven by logic and reason. Doing something that serves only to alienate people is illogical, as it brings no benefits and makes people less likely to be helpful later. While I have little empathy, living well with other people is a very good idea. Scratching somebody's back costs nothing and that person could also scratch my back when need it, perhaps when my arms will be occupied. I live by rules created by logical thinking, and it works. I see no reason (besides emotions and stupidity) why every person isn't doing the same. World would be so much better if everybody stopped to think. Unfortunately, it seems that simple, plain stupidity is the answer to why this guy did this, but it is also the answer why we have so many incompetent leaders and why freakin' countries start to bankrupt. Troll the wrong person and you end up in jail. Troll the right one and you end up in charge of the Ministry of Justice. In fact, the longer I live on this world, the more certain I am that all problems are fundamentally caused by human stupidity, and the fact there are more stupid people than intelligent ones. Unfortunately, no jail (perhaps except lifetime sentence, without a chance to get out) could eliminate stupidity.
