Interesting post.
In my opinion, God is us. God is both Good and Evil. Its the whole. We are God yet we have forgotten this. We disconnect from God because of our perception of individuality.
Evil is ignorance created by our ego which is part of God. We as humans create all the evil in the world because of our ignorance.
I was going to comment but this sum up everything I believe. The evil is the product of lack of love. About dying, diseases, etc, that's nature. Everything alive shall one day die.
