Does the idea that human beings after the end of their current embodiment (incarnated) are embodied again (re-incarnate) merged with karma, the idea that embodiments are based on the moral quality of the previous embodiments solve the logical problem of evil, namely God and existence of evil are logically inconsistent?
Let us assume that the doctrine of reincarnation that includes another doctrine of karma is true. Let us assume that Yajnavalkya saying in Brhadaranyaka Upanisad: “A man turns into something good by good action and into something bad by bad action.”(Upan 3.2.13) is correct. Does the moral justice unfolding itself throughout a series of embodiments solve logical problem of evil?
Agreeing with Keith E. Yandell, I think it does. A person who believes in reincarnation and karma can solve the problem of evil by pointing out that evil is a result of just punishment of bad actions(karma) from a person’s previous embodiment(s). Actions done in previous embodiment(s) can explain why bad things happen to good people or why infants suffer, et cetera and the verse.
Borrowing Yandell, a reincarnation and karma believer could argue:
For any evil E that occurs to a person in lifetime N, E is the just consequence of wrong actions by that person in lifetime N or in her lifetimes prior to N.(Yandell 1999, 124)
It appears that a person who believes in reincarnation and karma would have, if argued in such manner, succeed to show that God and existence of evil are logically consistent. The problem of evil is thus not a problem for those who believe such Eastern doctrines.

 Yandell and I do not believe that doctrines of reincarnation and karma are true.
