Slavery in the Bible

I’m having a hard time reconciling with the fact the Bible doesn’t condemn slavery, while I get slavery was a thing so it had to be regulated & if God outright banned it, ppl wouldn’t have wanted to follow Him, but even then the rules He made for treating the slaves & considering them property to be given to kids as an inheritance makes me feel weird. I am a Christian due to my belief in Christ, but the OT laws on slavery have me deeply sad.
