Fundamentally, the basis for thinking death is the “worst” is that so long as you’re alive you can still experience good things, regardless of your past, and you retain the capacity to heal in different ways.
Death is the one thing you’re not coming back from to find a new way to live.
This question implies death is the worst that could happen to you.
Personally, I don’t see it that way. There’s a lot more hurtful things than death.
Death is one occurrence, with no pain in the death itself, and “only” secondary pain in those left behind.
There’s a lot more hurtful and lasting pain you can inflict, physically and psychologically, and without a definite endpoint.
