deserting and pissoff. But why he hated rich guys? Anyway, he wanted to get his messages out or perhaps he just wanted to be known. He was hyperactive inward and hypoactive outward before the burst.
This Aussie who killed 35 in 1996 is a little different but there were similarities. He was regarded as a hemi-retarded person and was also institutionalized several times for his madness. But as far as I read he was not lacking of dignity. He said:"I'll do something that will make everyone remember me". That's not something coming out of a moron's mouth but like someone who has been neglected for a long time.

Perhaps none understood him therefore there was no way for him to be part of the society that he wanted.
