Depending on the religion or belief system, the outcome in the afterlife for narcissists or anyone else may range from eternal punishment to redemption, reincarnation, or even various states of spiritual existence.
It's essential to recognize that views on the afterlife are subjective and deeply rooted in personal faith and cultural perspectives. It's best to explore religious or spiritual teachings that interest you to understand their particular beliefs about the afterlife and the fate of individuals with certain behavioral traits.
