A common theme among the young, violent, mentally deranged is their submersion into dark themes and video games of slaughtering people. He reminds me just a tad like that Adam Lanza murderous freakoid from about a decade ago in CT. school shooting. That little crazy demon killed his mother too. This cretin today was driven also by his inner demons.
Maybe a predictable outcome of a generation (x) teaching their offspring for a generation that the earth was doomed (global warming)
