Koreans have the longest recorded history of slavery with about 1500 years under their belt. The Japanese are responsible for war crimes and genocide comparible to the holocaust. It's not just us that has a terrible history, it's everyone.

From the years 350-700 the Barbarians had a god of war. It goes back a long ways. The killing for, by and about god/s.

They have done it all and so has many other countries.

The Spanish brought the Inquisition to the Americas.

Not only America either.
