Wow... you are demonstrating the problem of how the default invites players to poison the social dynamic and can't even discuss it without twisting the point into something that paints the gm as some kind of monster killer gm.
I ran 2e and 3.x. even PC's died it was a neutral thing because everyone could accept that it was the monsters not the gm putting in "a bit of effort" to execute their pc. Back then there was always something that the party could have done different and after recap discussion wil likely do better at in the future, that's no longer the case when a pc is killed due to the bar being raised to one that looks like the same execution as the gm deciding "I want to kill off characters on a regular basis'. You aren't even responding the topic being discussed in either of my previous posts.
There's a vast spectrum between no-harm DMs and killer DMs. It is and always has been up to the DM and players where they end up on that spectrum. There are far fewer "Oops you're dead" options than there were in the past - you seem to ignore the many ways characters could die in the TSR era that could not be prevented. There were plenty of times when one of my characters died and there was nothing I could have done differently. Meanwhile the lethality of my campaigns I run hasn't changed much over decades of play, I rarely killed off PCs in back in 1e and it's just as rare for me to kill off PCs now.
Do the current rules limit how often characters die because of something out of their control? Yes, and I think that's a good thing. Meanwhile if my players wanted a more gritty campaign with higher lethality I could do that as well. What end of the spectrum people fall on has always been a preference and still is.
