I think that raises a different problem.For the people who don't like combats that just go: I attack, I hit, roll damage, I wonder how you all would feel about this kind of system if each attack might be lethal. I mean most modern fire fights are just people shooting at each other until someone gets hit. It doesn't sound all that exciting but I'm guessing (I've never been in a live fire fight) the people involved are pretty stressed about it.
Some games have a lot of one shot death potential and they make combat much more tense with big consequences. Low level D&D particularly older D&D, lots of save or die in old D&D or potential rocket tag in high level 3e, WFRP unless you are designed as a really tough armored skill focus warrior, Call of Cthulhu, Runequest, etc.
For many this takes a bunch of the fun out of combat and makes it something you want to avoid unless you are doing a big ambush or you know you really outclass your foes.
Tastes vary and some love this. I started with B/X and 1e and low level was easy to die through die rolls even doing everything in a skilled play fashion. Just check out the samples of play in Moldvay Basic and see how many of the party dies. Same in the 1e DMG with the gnome and ghouls.
Some love the Dungeon Crawl Classics 0-level funnels though where each player starts with four peasants and ends up with one first level character.
Others like me want to play action hero fantasy where combat is like a martial arts movie, engaging and exciting and fun with back and forth momentum without a significant risk of random death for a protagonist that ends the story prematurely.
