The problem of theodicy is at its basis the problem of evil. How can there be a God who is both benevolent and able to alleviate or avoid our sufferings, given that such sufferings are still there?

How can He exist, given that also infants and animals suffer, i.e., also creatures suffer, who cannot have deserved it? The role of karman cannot really solve the issue. In fact, if God cannot remove karman, than He is not omnipotent and Mīmāṃsā authors might be right in insisting that we should use only karman to explain present sufferings and avoid God altogether. If God could change one’s karman, but usually decides not to do so, then how can He avoid the accusation of being cruel?

Whereas the topic of theodicy is one of the major Leitmotivs running throughout the whole history of modern European and Euro-American theology and philosophy of religion, it is not formulated as a distinct topic in Sanskrit philosophy (for the similar case of free will, see
Freschi, ”Free Will in Viśiṣṭādvaita Vedānta: Rāmānuja, Sudarśana Sūri and Veṅkaṭanātha”, Religion Compass). Why so?

Part of the reason is linked to an accidental fact, namely the genius of Gottfried Leibniz, who wrote a Causa Dei `Trial of God’ and coined the term théodicée. Apart from that, the main reason for the relative absence of the problem of the contradiction between the presence of evil and the existence of God lies most probably in the fact that theism is a late-comer in the history of South Asian philosophy. In fact, in order to put God on trial for the presence of evil in the world, one needs the philosophical concept of an omnipotent and benevolent God, as it is found in Europe within rational theology. This is the kind of concept of God defended by some Nyāya authors, most typically by Udayana, and attacked by Mīmāṃsā authors, typically by Kumārila.

In fact, Kumārila’s attacks are the ones even later theists will have to be able to defeat. Kumārila shows that the idea of a God who is at the same time all-mighty and benevolent is self-contradictory, since if the Lord where really all-might, he would avoid evil, and if he tolerates it, then he is cruel. If one says that evil is due to karman or other causes, Kumārila continues, then this shows that there is no need to add the Lord at all as a further cause and that everything can be explained just on the basis of karman or any other cause.

The discussion on evil in the Ślokavārttika is prompted by a discussion on God’s creation. Kumārila asks why God would create the world:

prāṇināṃ prāyaduḥkhā ca sisṛkṣāsya na yujyate || 49 ||

The desire to create a world which is mostly painful for the living beings does not suit God || 49 ||

To the possible argument that God creates the world out of compassion, Kumārila replies as follows:

abhāvāc cānukampyānāṃ nānukampāsya jāyate |\\
sṛjec ca śubham evaikam anukampāprayojitaḥ || 52 ||

Given the absence of people to have compassion of [prior to creation], He could not have compassion |\\
And, if He were prompted by compassion, He would create only a splendid [world] || 52 ||

The next move of Kumārila’s opponent is found also in some Christian theologians, namely the claim that evil is not completely avoidable:

athāśubhād vinā sṛṣṭiḥ sthitir vā nopapadyate |\\
ātmādhīnābhyupāye hi bhavet kiṃ nāma duṣkaram || 53 ||\\
tathā cāpekṣamāṇasya svātantryaṃ pratihanyate |

[Obj:] Without evil, the world could not be created nor continue to exist |

[R:] Why would this be impossible, given that the instrument [to make it possible] depends on God Himself? || 53 ||
And if you were to say that He also underlies some limitations, than His autonomy would be destroyed |
