In most fictional portrayals, immortality is often depicted as painful because it creates a sense of unending monotony and loneliness. Immortality means living forever, and as time passes, one’s loved ones will age and eventually die while they remain the same. This can lead to a profound sense of isolation and grief.
Additionally, immortality can lead to a sense of boredom as one experiences everything life has to offer, leaving them with nothing new to experience.
The fear of outliving everyone and everything they care about can also cause intense emotional pain.
These themes of monotony, loneliness, and grief are often explored in fiction to showcase the psychological toll of immortality.
