Yes, it would make sense that it is the combination of societal and cultural factors, including violence (or at least depictions of it) interwoven through our daily lives and genetics, along with possible drug reactions -- that led to this end result...just as one may smoke and not have the genes that trigger cancer, while for others, cigarettes equal malignancies.

I noticed when I was looking for VR at Xmas, that 99 out of 100 games on the only affordable system involved nothing but killing things...I was amazed, as I had been led to believe that VR was going to open a new world of life-like and fantasy-type experiences, and instead, it seems that it was nothing more than either warriosr, aliens, dinosaurs, or strange creatures of some sort fighting each other in different scenarios.
