The potential impartiality is a crux of the issue with advanced robots. It would be very tempting to put robots in places of power: such as political leaders; soldiers (as in this case); policemen; and judges where their human counterparts could be tainted by corruption, prejudice, greed, ego, etc. But then if so much power is relinquished to robots, they could more easily overthrow humanity.
there is a catch 22 here
As long as we don’t want robots to overthrow humans, they are limited to making simple office works, without free will they won’t be able to make decisions in more complex cases... if we provide them with free will somehow (like delete 3 laws of asimov from they coordinates) we are putting the noose around our necks.
