Have to say, I think the way he handled everything wasn't just socially inept, it was psychopathic.
I think the misunderstanding between the common western "NEET" type we have on 4chan that we seem to familiarise with these types of characters is that our society is very different.
In that these types are people with heavy psych issues, in Japan, and they don't get help for it in Japan. What was that thing I read..... no psychologists in japan or whatever? kids basically rely on family and peers to get them through shit and if they can't they generally just go bonkers.
You have to relate a guy like this to that of the columbine shooters but in a different category. The extremes they are in are comparable.
It was annoying to watch him do stupid shit over and over. but if you see it that way, it helps convince you that you didn't completely waste 10 hours watching this.
