slavery do not always mean that you can kill someone.
Many times in history when slavery was legal, it was forbidden to kill the slave, in fact when slavery is NOT legal that this is more frequent (for example here in Brazil, I already did some research on present day slavery, and here most slaves end dead, usually killed after they are not useful anymore, so that they don't tell the police about the slave owner).
I think that yes, being allowed to arbitrarily kill anyone (pay attention to arbitrarily) is evil, this applies to US drone strikes. But arbitrariety is not evil, neither is kill someone, the combination of them that might be.
Would you be allowed to make your slave eat off the floor because he/she did not work fast enough or refused to perform a sexual favor for you?
Would a slave be able to terminate the arrangement under some conditions?
If the slave believes that they are being treated in a way that violates the slavery regulations do they have a right to bring charges against their master, do they have a right to legal council (if so , who pays)?
What about offspring of the slave, can the master decide who the slave will breed with (if at all). Do the offspring of the slave become property of the master?
