Gods immorality.

[SteveII]

I believe it probably happened.

However, what is your point? That God doesn't exist because he commanded such a thing? That does not follow. That God is a monster? To support that, you would have to assume there was no reason for these actions. Can you do that? Can you put yourself in God's head?

Related to this, why do you think God is under some kind of obligation to extend or preserve life? There is no basis for thinking that. Do you think humans have "rights" in relation to God? That would be to vastly misunderstand what it means to be God. 

Lastly, I won't comment on your friend, but do you really think these issues have not been brought up before (especially among Christians) for literally thousands of years? Do you really believe that there is not a ten thousand pages written for every objection you can come up with? Your arguments are not new and they are not persuasive to someone who allows for the possibility of God's existence and really tries to understand how it might all work together.

From that piece of drivel you posted:

The framework for my ethical theory is what is called divine command morality. What is that? That is an ethical theory which says that our moral duties are constituted by God’s commands. It is God’s commandments to us that give us right and wrong; that determine what we should and should not do. Therefore, if God issues you a command to do something, that becomes your moral duty and it would be wrong for you not to do it. 

This is an absolutely hideous way to think.

Why? What basis would you have to say that God's analysis of a situation and the correct course of action to follow is wrong? How could you second guess an eternal entity that is omni...everything and whose character is essentially good (moral)? Show me where this is internally inconsistent. I was only pointing out that there are answers to the question the OP brought up and certainly not proof that God does not exist as suggested--only that his "christian" friend was obviously not well informed.
