Free will is not involved in every death, obviously. Accdents happen
What about the freewill choices of the driver effecting the fate of the children ?
accidents just don't happen, people make choices that lead to them...(cause and effect.)
Actually accidents do happen. The world is not deterministic. That said, free will choices also happen.
Theology divides evil into two types: natural and moral. Natural evil are things that happen when no free will choice is involved. Moral evil is the result of evil free will choices.
