Why does evil exist in Hinduism?

In Hinduism, evil exists as a natural part of the cosmic order, often seen as a consequence of karma and the interplay of dharma (righteousness) and adharma (unrighteousness). The presence of evil allows for the exercise of free will, enabling individuals to make choices that ultimately lead to spiritual growth and liberation (moksha). Additionally, evil is often viewed as a necessary counterpart to good, creating a balance in the universe and providing opportunities for learning and transformation.
