What I said is hardly disingenuous. People spree-kill for a whole gamut of reasons, which may or may not be related to various social factors. The unfortunate fact is that we're all, whatever our "neurological" status, only a step away from doing something similar when we lose our tempers. Trying to attribute blame to one or another factor is a fool's errand, because it will vary from person to person, dependant on the experiences of that person, even within a particular group, whether that group be people with AS, people with blue eyes, or people from one or another of the social classes.
The best we can do is analyse cases after-the-fact, and try to learn from them, as to how much particular stressors influenced their own spree-kill. This is why, compared to learned papers on serial-killing, spree-killing is an under-interrogated phenomenon -it's unpredictable in a way that serial killing isn't.
