I highly recommend everyone here to read Harlan Ellison's "I Have No Mouth, and I Must Scream."
There are fates worse than death, y'all.
If a megalomaniacal all-encompassing artificial intelligence had the ability to trap you in a living nightmare, kill you, bring you back, kill you again, and bring you back again for 500 years with no inkling of slowing down.... yeah, i think you'd be begging for that sweet release.
