Why arbitrarily force your player to make a new character if they are enjoying playing their character?

So make up any other reason your character has to leave instead of your DM deciding when you are done playing.

Players don’t NEED anything.

Some players want a challenge and to feel anxious when playing tabletop games.

Some don’t want the threat of their characters dying, or a stressful experience when hanging out with their friends.

Personally I want to be then one that decides when I stop playing my character that I spent hours making and flushing out, if my DM killed my character for some random bullshit dice roll i would honestly not want to play anymore.

Unless your players are complaining about their characters not dying it’s probably a bad decision to kill their characters.
