I think that there is no hell but there might be heaven. IMHO the God can't be that vindictive as to condemn his children no matter how horrible is their crime to the eternal tortures. But as long as He is omnipotent He can arrange special heaven for the chosen ones.
IMHO His worst punishment would be the eternal death.
The next punishment would be the curse to children.
Take Hitler or Lenin. They both had no children. The lesser evil Stalin had children but the God's mills are slow. The damned would be his childrens' children.
