>did slavery exist in middle earth before the war
Definitely. But think about it this way: the only sane people left in Middle Earth were humans, dwarves, hobbits. Humans control the strongest army. Aragorn would be a fool to not conquer and enslave all those who attacked them: the remaining orcs, trolls, and pirates. Letting them live and regroup to attack later would be a massive strategic mistake, seeing as they multiple at much faster rate than humans.
W-wait a minute ....
