There's a new-school of player/GM culture that says that having a character die is the worst thing possible. From my perspective, it's far worse to lie to your players than to kill their characters.
Part of the fun is overcoming the risks and beating the challenges in your way. If your GM is making it impossible to lose, did you really win?
If you want to play a game where death isn't a consequence, that's an option too, it just isn't true of the majority of TTRPGs.
The important thing when DMing is to never let the players know if there was fudging going on. Fudge in secret if you need to, but the moment the players know there are no consequences then there's suddenly no reward.
l mostly agree and i don't really ever fudge, but i don't really like instant death, as it's mostly just luck. If they die from poor choices or failed death rolls i don't mind, but like, i've had players at full healh "die" because the monster rolled a crit and the highest number on both damage rolls. I ended up just downing him and giving him a cool scar after he got up cause that's bonkers and it was literally the first fight of the campaign, lol.
I might make changes to the number of monsters or their stats, but that's always something i do before the fight, never during it. Homebrewing is alot different than fudging imo. Once the players have seen it, it's set in stone.
dice are only there to make noise behind the GM screen
Rules are just suggestions
PC death shall not be the result of bad dice roll, but a consequence of player actions one of my classic fudges to avoid it is to suppress the critical rule, and to replace single die system by multiple dices to have outcome easier to predict
