Death was not part of God's creation. It is part of the ToE, in fact essential to it, it is driven by death.
You've mentioned death and suffering alot throughout this thread. Are you thinking specifically about humuan death and suffering, or do other animals count too?
What about plants? They may not suffer as we think of it, but they certainly die. Did micro-organisms also live forever? Did no one ever stub their toe in the garden of eden?
And I think that death most certainly was part of God's creation. He created a heaven and a hell for everyone to go to when they die.
Fianlly, do you think that death necessary?
