Theodicy can be defined as a branch of theology that deals with the study on how the being of a benevolent God is made consistent with the being of evil. An effort to accommodate the co-existence of God and evil is occasionally referred to as a theodicy. Free Will Theodicy presumes both man and God possess utmost free will. The premises of the argument to which Free Will Theodicy is a response are: If a perfectly good and all-powerful God exists, then evil doesn’t exist; evil exists in the world; and therefore, a perfectly good and all-powerful God does not exist. Human beings were created with morally substantial free will and this shows that God really did something of great value. It was not a good option for God to eliminate suffering and evil because by so doing He could have eliminated the greater good of creating human beings with free will who can create moral choices. In this case freedom is meant to give a morally adequate reason to why God allowed evil.
According to free will theodicy, evil does not have root cause. This free will that God gave to human beings does not turn toward evil but it does turn away from Him. Evil comes into existence only when the will reverses towards something base. It is clear that, it is the act of the will turning itself away from God that is regarded evil. Natural evils for instance diseases and earthquakes are occasionally considered problems for Free Will Theodicy because they don't appear to happen due to free decisions. The probable reasons for the occurrence of natural evils comprise of being caused by the free decisions of spiritual beings such as demons; being caused by original sin which is successively caused by free will; being caused by natural laws that have to run as they do for the free and intelligent agents to exist; or that by copying and observation they enable human beings to do more evils, which lets moral decisions more important.
The most familiar theodicy is the free will theodicy. This is concerning the fact that God created evil so that human beings can have the opportunity to choose between good and evil, in order to make moral choices. If for example all options result in good, then it is true that moral choices would not have existed. A good example is choosing from love and hatred, in that on condition that love is acceptable, it has to be chosen above hate and for that reason suffering and evil result when we compose morally poor alternatives. God permits evil in order to bring about a more perfect universe. This needs humans to be provided with free will, and occasionally they misuse this great gift. The world is the best place by the fact that God accorded his creatures the freedom of free will. Suffering and evil are the opportunities that given by God to enable growth of human beings in goodness and virtue.
God being omniscient means that He is all knowing. An omniscient, totally good God would avoid the occurrence of any extreme suffering, unless He could not do so without thereby doing away with some greater good or allowing some evil that is equally bad. God would avoid the destructive consequences from really happening; or if destructive consequences happened, then God would occasionally or at all times instantly penalize such acts, and this would presumptively decrease their frequency of occurrence; or the biggest diseases could have been avoided, as well as adequate resources could have been accessible to humanity, very extreme pains either could not develop or could be switched off as they have no purpose.
