There is this anime series called From the New World. The premise is a portion of humanity gained psychic power and led to the collapse of society because it's so powerful that order could not be enforced. Far into the future there's a cluster of community that's able to exist, and the way they went about it was to genetically engineered humans so that they when they harm another human it triggers body functions that make it harder for them to breath and other things. Killing another human also kills the aggressor. It kind of works on the interpretative level so it's possible that using drone could still have an effect, probably.
