As the title says, what act of immorality or cruelty is considered completely normal and common place in your world?

I have a few from my World

Imperial:

Imperial Slave Spawners: first take a dozen or so female members of a slave species, fuse their wombs together, and pump them with hormonal treatments and hyper fertility implants.
then you fertilize the Spawner, and wait a week. You then get batches of up to 60 new slaves. then you fertilize the Spawner again and again until the Spawner dies. then you do the whole process over again.

Tronarian clothes/ food: The Imperials enslaved the Tronarian species (avian Xenoform)so they could pluck their feathers and then eat the avians.

the feathers are used to make the latest fashionable clothing ( even though they are advanced enough to just replicate the same feathers synthetically), and the misery of the avian as they are plucked feather by feather is said to add to the flavor when they are eaten alive.
Due to this, it is considered a curse to be attractive in that species

UNID:

Resocialization: which is a basic therapy that can treat anything from depression to PTSD.  It just slides false memories of being loyal, patriotic and happy over your actual memories. The government creates documents that match these memories to sell the farce.

99% of all Directorate citizens have been through Resoc.

there are also more intensive ones that remove your memories and replace them.

A person who went through Resoc doesn’t remember it.
