One sentence that throws the problem of evil out of the window.

[Kernel Sohcahtoa]

Nope, not objectively wrong.  But, and this will look like exactly the same thing, it just so happens you will find near unanimity of agreement that those things are wrong subjectively.  The fact that it is only near unanimity accords better with the evil being a subjective phenomenon than an objective one.

I think the opposite. I think the fact that there is such a  universal consensus through all cultures and countries that certain things are wrong, supports the belief that morality is objective and that we have an inherent understanding of that. No other "opinion" is so universal as it is when it comes to these black and white moral issues.

IMO, after reading your post, it would seem that people are the primary source of "the universal consensus through all cultures and countries that certain things are wrong".  Thus, if people ultimately acquire their morality via human interactions/teachings, then why can't humans be the objective basis for human morality (religious, non-religious, or whatever).  Also, since context plays a key factor in any effective ethical/moral system, then why is it problematic for there to be a subjective component to morality? Regardless of the type of moral system that one adheres to, if the success of that system ultimately depends on the behavioral choices and actions of humans, then is it not logical for humans to own that system and tweak it as they continue to progress and evolve?
