I would argue that anyone who adopts these values is a slave to themselves, controlled by whoever claims to share these values but in fact uses them for control. These values no longer serve our self-interest or nature, and as the entire point of values is to make judgement of relative "right" and "wrong" from one's own perspective, we should be free to mold them as need be.

Religious values serve to externalize one's own will to a "god." This rationalizes why nature is able to get away with what is "forbidden" (for the purpose of making the masses feel guilty and fall back to the priests for forgiveness). When we realize that values are not absolute, and can be molded according to individual will, we do away with the need for a "god" to externalize our personal moral preferences.

As Nietzsche said, when god dies, we must each become a god unto ourselves, or try to lie to ourselves that god still lives and remain slaves to the externalized will of the long-dead others who invented him.
