Spira (FFX) - So if I die, I either get sent to a paradise world in the Farplane, reincarnate into a snazzy monster that can eat people, or transform into snazzy Jedi Zombie that can't be killed and is 10x more powerful than when I was alive? Seriously, why are people fearing death in this title again? When you kinda have a guarantee how the afterlife works, I can't imagine why death is considered a big deal anymore. Despite the rampant death, its trauma is negated by the afterlife system being more cool than terrible.
Your FFX hate is showing. >>

People probably fear death in Spira for the same reason they fear death in real life; it's human. It doesn't matter if you kow, or think you know, there's Heaven after you die. You still don't want to die.

And thinking about it more unselfishly, I'm sure the possibility of starting a family and then having your kids killed by the giant unstoppable monster is a source of great fear.

Honestly Spira as of FFX is the most depressing and grim place to be in any FF game short of the World of Ruin.
