Perhaps he could just not create beings that are fundamentally flawed so that he has to send them to an eternal damnation.Are you saying that any individual who does not wish to love and serve God should be forced into heaven to love and serve Him anyway? For an eternity?
The perfect, all loving and all knowing god could easily pull that one off. And I would bet that it would not even need to kill all of its creations in a massive flood to make it happen...
