Your assertion that morality can only be objective in a universe created purposefully by God, seems to indicate that you fall into the first camp. But I don't think you do. I think you accept #2. But as a thought experiment, let's follow conclusion #1 to its logical end. Let's say that God comes before you and tells you that (if you want to) you can murder your neighbor's wife. If you do this, you won't have to ask for forgiveness, there is no threat of eternal damnation--none of that. God has said that it is okay.
The question is: would you kill your neighbor's wife if God allowed it? If God allowed it, would that make it morally right? If the answer is no: why not?
Maybe it's because killing this woman would deprive her husband of a wife, and her two children of a mother. Maybe it's because it is her life, and you don't have the right to take it from her. Maybe it's because she is a human being with dreams and aspirations, and your desire to kill her is superseded by her right to live. But if God gave you permission, would any of these reasons that murder is wrong change?
Morality can neither hinge solely on the utterances of God, nor is it in any way impacted by God's purposes in creating the universe. Otherwise, murdering someone would be somehow become morally right just because God allows it (even though, by any other metric, it is the exact same deed). And (assuming there is a God overseeing this universe) it would become morally right to commit murder in an exact carbon copy of this universe if said universe were to come about by happenstance.
No, there is a third way to look at this.
3. Murder is wrong because God forbids it. God forbids it because it runs contrary to his nature ('nature' as in cannot be separated from the whole of God and so definitionally all of God's commands must be consistent with his nature). Not only is God's nature good, it is the paradigm of goodness (as the greatest conceivable being). Therefore murder is objectively wrong ultimately because God's unchanging nature has determined it to be so. Additionally, you don't have to actually know that God forbids it--he wrote basic morality on the hearts/minds of all normally-functioning people.
