Because there is no "you" to ascribe them to in the first place.
If we disagree, that much, at least, we have in commonIt may seem pedantic at first, but making that distinction actually does lead us to different conclusions about the "meaning" of death, so it's an important distinction to make.
Here's the thing, unlike most people here, I do value what occurs after I'm dead. The sooner I die, the less of a positive impact I can leave on this world. Define positive impact you say? No, it's just want I consider to be a positive impact. Now, I can honestly say that what I do on my day to day basis is, in fact, positively affecting people around me, at least more so than I do harm.
And when I'm dead, hopefully some of the people I've helped will hold onto something that I gave them and push them to do the same thing.
See, death isn't scary, it's just a severe annoyance. It's stopping me from what I want to do unto infinity and so long as I consider myself to living a positive existence (which, you know, I felt I was even when I was digging out of dumpsters to survive or using the school gym as my only means to a shower) then being non-existent is quite a step down.
The emotions of others can seem like such well guarded mysteries, people 8egin to 8elieve that's how their own emotions should 8e treated.Well certainly, if your existence is a positive thing compared to not existing, you certainly want to continue existing. No one's arguing against that. ATM anyway.
There are not traits, positively or negatively, we can accurately say are possessed by "you" when you are dead, except in abstraction.
