I had an anime recommended to me. The MC sells two people into slavery in the second episode.
(hexbear.net)
The world's most notorious "talker" runs the world's greatest clan
Should've known from the light novel ass title 
I actually did like the MC's abilities because, yeah, you don't usually have what's basically a bard or skald as the protagonist, but yeah, if you're not into isekai/fantasy power fantasy slop with edgelord "slavery is okay if they like, stole all our money" type bullshit going on then yeah idk why this would be recommended, it's sloppy slop
