This is not so much the fault of the soldiers who shoot without thinking of the consequences, as that of the governement who brainwash them and teach them to hate the 'enemy' in whatever size or shape. It's an old strategy of domination through instilling hatred: Stalin did it against 'revisionists'; Hitler did it against Jews; Maduro in Venezuela is doing it right now against 'businessmen'; the Israeli governement is doing it to Palestinian children with impunity. Unfortunately this old strategy still works.
