Very few people that die 'made peace with their morality'. Why is it a prerequisite? How do you assign value to another person's life simply based on if they made you cringe or not? That's cringe.
If the rotating cloud of gas and dust stayed forever, there would be no Earth. If the chemical compounds would be super stable, there would be no life. And so on. Systems are kept in equilibrium by this, otherwise they became unstable.
Making space for the next, better entity is a cosmological principle.
If you can't make peace with that, I am sad for you.
It's not some deep philosophy, it's basic science.
The tapestry of live consists of all the individual threads (lives) and if someone of those threads never ended, new threads cannot be in the space they occupy. That's trivially true. And to me that does the same to the tapestry of live what a cancer cell does to an individual body.
We already have shit like, let's say, old people starting a war of aggression over oil and profits for Halliburton et al, and then torture someone like Assange, who is still not free. And that's even though they'll only live for a few decades at most! If they knew they could potentially live hundreds or thousands of years, the gloves would come off in ways you cannot even imagine, and if that's "2deep4u" or "conspiracy theory" for you that's great, don't bother telling me.
