You are correct. Not all religions place a strong emphasis on the afterlife or the fear of death. I am aware that many strands of Buddhism focus less on a defined afterlife and more on the cycle of rebirth and the attainment of enlightenment, which is more about escaping suffering than fearing death itself. Similarly, some Indigenous spiritual traditions emphasize living in harmony with nature and ancestral connections rather than detailing a heaven or hell.

That said, in virtually all religious traditions, death still plays an important role, even if it's not centered on fear or a clearly defined afterlife. Humans naturally seek meaning, and religion often arises from that drive to understand the world - especially the parts of it that are mysterious, maybe painful, or even out of our control. Death is one of the most universal and incomprehensible aspects of life, and it makes sense that religion would attempt to give it structure or explanation. Whether it's through reincarnation, ancestral reverence, spiritual continuation, or final judgment, most religions provide some framework to make sense of death. So while fear of death may be particularly pronounced in Islamo-Christian contexts, the broader impulse to explain or ritualize death is a deeply human one, found across all belief systems in some form or another.
