For me, being spaghettified by a black hole would be the worst way to die. Imagine being stretched out over days, weeks, or even months. You experience constant pain and you can't do anything.
This might sounds edgy, but I think living forever is worst than being spaghettified. You outlive all of your relatives and offspring, you see everything that has, is happening and will happen. The emotional toll would be too much to bear.
