Personally, I would not think that death were necessarily a telos, even supposing our being-a-whole is a telos and achieved through our relation (of freedom toward) death, but I'm guessing many people do think of it that way
Authenticity requires that death be achieved not as an endpoint, but as an origin and telos of life itself

Does Heidegger believe in a human or life telos, and if so is it only death?
I am asking because of the idea of life as a series of roles, and if its purpose and end is only to not exist, then I'd have thought we couldn't make them our own, that we can find neither space for rebellion, nor to consider anything beyond how well we play our role (not e.g. to what end).
Telos is the ancient Greek term for an end, fulfilment, completion, goal or aim
