I am not disagreeing with you theologically, but legally I am. Evil is an opinion based word.
There is both objective and subjective evil. In general, harming (including enslaving) another person solely for your own personal benefit is an objective "evil" by any definition of the word. Subjective ("opinion based") evil would include violations of moral and ethical codes that are not univerally subscribed to.
