We are born with an innate sense of fairness and justice. Young children, e.g., can readily make judgements about what is right and wrong long before they've been indoctrinated with religion or ethical training. So can my dog, for that matter.
Judging that slavery was "right" wasn't as arbitrary or as easily done as you assume. Society didn't decide that "certain people don't deserve certain rights" so much as it refused to recognize slaves as "people". They were considered property, more akin to draft animals than humans, and thus the moral standards we apply to human relationships didn't apply. Dehumanization is the key. You see much the same thing with the "illegal immigrant" issue in the U.S. today. In order to justify the level of brutality that many conservatives believe is warranted, it is necessary to demonize them all as dangerous criminals, when the truth is that most are hard-working people who are contributing far more to society more than they are able to claim in return. So innocent children are not to be educated, the sick are not to be treated, and labor is not to be fairly compensated. And Jesus is entirely OK with this, because they are all (even the children) "criminals".
The relationship between religion and morality/ethics is by no means straightforward. While it may be true that some people are constrained in their behavior by their understanding of their God's demands and threats of punishment, it's also true that God can be used just as easily to *override* our innate sense of morality and justice. We are allowed to deny basic humane treatment to heathens who don't worship as we do, just as we're allowed to deny it to slaves and others who we've dehumanized.
