If some mystical being called "god" really punishes people for previous generations mistakes. How could "it" get upset when people are mad?

I don't see you question represents a valid dichotomy. I Believe in God, I also believe in evolution as defined by the broad scientific community. I also recognize that evolution so defined is inconsequential to the question of God's existence,or even creation for that matter.

I would also assert that those forward the notion that God V Evolution is a valid dichotomy are obviously confused. God is an ontological entity, evolution is a natural process they are not even in the same category. Your question is akin to asking do you believe in yellow or poetry.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
