There is a large base of research on this problem for the US military (and CCCP etc). i.e. How to discern effective killers within troops, how to shape them and how to 'uplift' the usual grunts to effectively kill.

I suggest you research "natural killers" from 1946 onwards (famous paper starts the ball rolling there - Combat Neuroses / Fatigue is a tip). Their percentage increase in producing effective killers is impressive. I won't link to specific papers, since it's outside the remit of H.N., however a lot of hard science & tech has been brought to bear on the issue.

The flip-side of this, the mirror to a sociopath (let's call it "the empathetically linked / driven") makes just as an effective killer for the record. If not better.

Tl;dr

You're about 70 years too late to pioneer this field. However, in looking @ the current trend to map Autism onto AI networks as a model, I'd suggest you'd probably have more joy looking at the empathetically linked individuals to see how their strong network connections / protective instincts are harnessed if I were to build a neural Map (weak) AI.
