The presence of evil in the world and the cause of evil; How does God Allow it?

We are going to refute the argument of Vexen Crabtree that he can effectively explain the cause of evil in the world or possible lack of ways to define its existence by the absence of good and how God/man reconciles that.   Listed here is an excerpt from his website:  

If God is all-powerful and all-good, it would have created a universe in the same way it created heaven: with free will for all, no suffering and no evil. But evil and suffering exist. Therefore God does not exist, is not all-powerful or is not benevolent (good). A theodicy is an attempt to explain why a good god would have created evil and suffering. The most popular defence is that it is so Humans could have free will. However the entire universe and the natural world is filled with suffering, violence and destruction so any Humanity-centric explanation does not seem to work.”

The Absence Theodicy is the argument that as God is "goodness", anything that is "not good" such as evil and suffering, is simply the result of the absence of God. Therefore, the absence theodicy (attempts) to excuse God's responsible for evil, by trying to discretely contradict the principal of God's all-powerful and omni-present nature.  

His argument does not take into account that God does not attempt to control each human decision nor does it present a case that God cannot be lacking in an omni presence just because we live in a fallen world chosen by man.
