There is such a thing as criminal negligence in choosing and attacking enemy targets.
But no, adding a whole bunch of emotional baggage to the act does not suddenly make any collateral death a war crime as you imply here.
Bombing runs are woefully innarcurate though, so the good thing is when we have better weapons we'll start using those instead. Unlike insurgency groups who will often kill civilians as a means. Think that was partly the above poster's point.
