evil is not created, like darkness is not created, darkness is lack of light, likewise evil is the separation from good and since God is the source of all goodness when human chose by their free will to disobay God they separated themselves from him thus deserving the death sentence which is a normal consequence of separation from the source of life who is GOD, thus evil was brought into the world..

Hope this makes sence ...
