Berric Dondarrion did mention that every time he's brought back, pieces of him are missing. Literally and figuratively. He's missing an eye, and apparently he can no longer remember anything prior to being sent to the Riverlands to capture the Mountain. Jon has likely sensed that being the case with himself, and doesn't want to be continually brought back, each time a little bit less himself.
As opposed to death/nonexistence. Lose a bit of yourself or all of yourself. Doesn't seem like much of a difficult choice there
In the preview for next week, they showed him telling the Red Priestess to not bring him back if he falls. He may be emotionally affected at having seen nothing when he died, but clearly he isn't that afraid of it if he's willing to not come back.
I did actually post a response to earlier before reading below. Still all mostly conjecture other than Jon stating he didn't see/remember anything from after he died and our clip from the preview of him asking Melisandre not to bring him back if he dies again.
Can buy it. Did anyone ever ask Beric what he has seen? I can't remember. I still think he feels like getting killed was him failing, and he hasn't come to terms with that, more so than being afraid of death. If he was afraid of it, it wouldn't make much sense to be leading an undermanned army to try and reclaim Winterfell.
It's just a good guy, hero, martyr trope. Not worth getting worked up over.
Nah he already did his hero's sacrifice, albeit unwillingly. It's just crap writing to build artificial tension among viewers and I'm getting worked up over everything this season, so this is no exception.
