Since I mentioned it in the previous post, let me present an idea of an alien way that omnibenevolence could exist, which is not addressed in religion.
An omnibenevolent deity could create every possible reality, thus ensuring that all possible persons that could exist do exist at some place and time, in some branch of the multiverse.
Obviously, this allows a great deal of suffering and evil, and also creates an untold number of religions that are false, because someone that believes in a false religion is a different person from someone who believes in a true one.
That might be against our intuitions - we might say that a life which knows only pure torment is not better than never-existence - but it does look more like the kind of alien value that a true omnibenevolence might have.
