One of the major arguments proposed against the existence of God in contemporary western philosophy is the problem of evil. It is based upon the inability to reconcile the magnitude of evil in the world with the all-loving nature of God. John Hick
describes the problem from the perspective of its proponent, "If God is perfectly loving, God must wish to abolish all evil; and if God is all-powerful, God must be able to abolish all evil. But evil exists; therefore God cannot be both omnipotent and perfectly loving."
This thus causes difficulty for the Judeo-Christian-Islamic God who possess both qualities of being all-loving and omnipotent. David Hume is a proponent of this view and argues that the sheer amount of evil, which may outweigh the good, in the world makes dubious that a deity exists. The main response to this kind of an argument is known as the free-will defense. It is based on the premise that for God to create self-directly and independent agents like humans, he had to grant a certain amount of freedom to them, and this freedom would inevitably result in human-to-human evil.
It has been proposed that there need not be a contradiction between God creating morally free agents and making it the case that all their actions turn out to be good. But it can be argued that in that case, are the beings really as free as humans? If all our actions were predestined in this way, there would be a sense in which we would not be free and only an allusion be created thereof.
Although God could have created beings of this sort, they would have amounted to mere puppets and not vibrant beings as predicted by God.
... case in the present world in which we know given certain conditions person A would hypothetically engage in a morally evil action. It would no be impossible for God to create a world that were almost identical the present world, except that the person would then not engage in the evil. Since, to do so would deny him the freedom of individuality and his personality. That is, for God to ensure that he not engage in the evil would deny his freedom. The only other solution is for God to not create the world at all. He argues that for any world God could create, which included freedom, there is at least
one action on which Man would go wrong, or else he could not create any world at all. This phenomenon he calls transworld depravity. Therefore, for God to create a world in which humans had moral freedom, the existence of both Good and Evil is
