I agree that the killer robots on the horizon won't have a will to commit atrocities (though I'm not sure what an AGI killer robot might do), however, I must note that this is a tangent.

The meaning of the term "atrocity" in my statement was more to indicate things like genocide and oppression. I was basically saying "humans are capable of revolting in the event that a tyrant wants to gain power whereas robots are not".

I think I'll replace the word atrocities for clarity.
