Q3: I think that the atrocity of abusing and repressing African culture towards the enslaved people was a way to feel power. A large amount of people in power abuse it for their own gain. Think of the corrupt police officers never being held accountable. By having someone inferior around you, you will be the superior one. This is the same case with a master with his enslaved house servant. Someone worthless with "no culture" will fuel your narcissistic ego.
