Of course that still gives you a lot of leeway. Just what is normal for your world? Is it normal by the standards of our universe? If not, why not and how did your normality come to be accepted as such?
On a horrible note, slavery was (and sadly can still be) considered normal, when it definitely should not be. While Wilberforce and the Quaker movement achieved a great deal, slavery sadly still exists. It it just that certain countries no longer practice it, which is of course welcome. So is there something like this happening in your setting? A behaviour once considered normal no longer is? Who got it abolished (or at least practised rarely) and are they seen as heroes? (Wilberforce and co would not necessarily have been seen that way).
On a more positive note, has your world been set free from, say, slavery in itself and is now rejoicing in that freedom? How have the peoples of that world developed over time? Are standards of normal education higher or lower over the course of your world’s history?
Definitely story ideas to be found in there!
