They may well be psychotic, but you can't say they would be doing this sort of thing anyway.
Yes I can - I just did.
Maybe not in that exact, ritualised way, but they'd be in a gang, drug pushing, pimping, whatever. There are plenty of sink estate kids who go that way - but they don't end up killing people. But some do. Whether the gang chooses them, or they choose it, they **** up other peoples' live with insane violence.
True, but what happened yesterday is surely more extreme than falling into a gang culture, pimping etc.
