Personal choice. There are players who do 'permadeath' runs.

you can i was not really doing that in my worl and made itto day 68 almost to kill boss 2 before i had my first death to a dumb grayling

I mean, in any game. Die, delete character....

there may be a mod for it. You can also do the honor system.

a question looms: can you restart with another character? If so, you can find all the homes/bodies/etc and get a bit of a restart so that may be against your idea or not.

Heres what you do for hardcore mode. when you die. delete ur char.
why do they need to do it for you?

Make your own rules. Follow them. It's a sandbox. No one will care, no one will know unless you feel the need to inform strangers about how you play.
