Can you give a reason why we shouldn't cure death that isn't vague mystical equivocation? People are not seasons, they are not days, they are not stars. We do not need to "deserve" immortality, we just need to be able to make it happen.
Death sucks. It would be better if it didn't happen.
It's worth reminding that we cannot be immortal. We can only live indefinitely. But the universe will eventually see to it that we will end. Most models of the cosmos say so.
Barring some discovery that allows us to hit the reset button on matter and energy every trillion or so years, time will end for us all, no matter how long it seems.
Well yeah, the universe being finite sucks as well. Maybe we can't ever change that, but that doesn't mean it wouldn't be better if we could.
You talk about death as it is some kind of disease... Dead is part of life everywhere you look and not in the disease sense. There's a cyclic constant in all nature. You have seasons. You have day and night. Even stars that "live" for millions of years wither and "die" at some point. Why do you think we, as humanity, deserve to be the exception to that rule and escape a cyclic order that's been around like... forever?
Also, "life" feeds from "dead", no the other way around. It's not a coincidence that it's this way...
