First, you must let go of the idea that death is a permanent condition. It isn't.
Second, that God is the cause of the suffering we face, even if just by his ignorance. The truth is, God is not the total cause of anything. As noted already, creation happens even by continuation of evolution, including evolving into beings than when merely mortal. We are more responsible, ourselves, for human suffering than God is, or ever was.
Third, We are allowed to be agents unto ourselves, we are not the puppets of anyone. Having our own agency, we are the primary cause of virtually all our ills. Case in point. We can change building codes to resist the power of wind and rain to destroy, of earthquakes to destroy, but we have a hard time controlling ourselves. We could build an aqueduct from the confluence of the Mississippi and Missouri Rivers to the southwest. Why don 't we? Is that God's fault? We could easily desalinate ocean water for drinking. Is it God's fault we do not? We could actually use most of the food we harvest instead of throwing it away because we have poor distribution methods. Is that God's fault? There's quite a lot of misery-causing things we do that we could solve tomorrow if we could spend the money doing so instead of feeding and housing and educating the poor at the other end of the scale. We could innovate artificial organs for transplant instead of a black market. We could properly irrigate, cultivate, plant, grow and distribute food sufficient to feed the world, and then some. Why don't we, and is that God's fault? Stop blaming God until we have done all that we can do. We're barely scratching the surface because we turn our free agency in to greed.
