Divine Command Theory is Blackmail? Natural Consequences.

Natural Consequences:
Many believers argue that hell is not a threat, but a chosen consequence of rejecting God’s love and, by extension, good itself. In this view, God is not "blackmailing" people, but offering a choice.

Goes against the free will claim, the Isaiah 45.7 claim, God creating the opportunity to do bad before our existence and knowing about it. Are there any other problems with the Natural Consequences in Divine Command Theory?
