Morals - Objective and Subjective

[JuliaL]

Theist quite frequently use the argument of objective morals to justify the existence of a certain deity.

Let's distinguish between objective morals and absolute morals.
Objective morals are those which are agreed on and consistent for a set of individual observers. Absolute morals would be those which are external to and consistent for any and all individual observers.
I believe the former evolve with the societies in which they embed. Theists often claim the latter as the product and property of their particular deity who has rights to amend, enforce, or except in individual or universal cases. I do not believe absolute morals exist as anything more than a convenient fiction.
Objective morals are context specific to the society, species or self replicating informational organism to which they apply. Much like beauty is in the eye of the beholder, morally correct is in the mind of the individual. As an example, I have no doubt that a she-wolf protecting her pups against a marauding human child thinks herself fully in the right to maul the little bastard before it hurts her babies. Other wolves would likely agree. The kid's parents, not so much.
