I was thinking of this - Yes, slavery is bad. But is there truly nothing worse that can be done?

I’m guessing it might be because slavery was institutionalized over such a long period, that the generational exploitation makes it worse.

Once several generations of a lineage are treated like property, I guess one could argue that it’s worse than a single murder. Now, extrapolate this past a single individual/lineage, and I would reason that along the same logic, slavery is worse than genocide.
