Theodicy is a philosophical and theological concept that seeks to explain why a benevolent and omnipotent God allows the existence of evil and suffering in the world. It addresses the conflict between the belief in a good God and the reality of pain, injustice, and hardship experienced by humanity. Various approaches to theodicy include the idea that suffering can lead to personal growth or that it serves a greater purpose in the divine plan. Some argue that free will granted to humans allows for moral choices, which can result in both good and evil actions, contributing to the complexity of existence.
