It's dangerous at night. And if you are in a position to not have a plan for corpse recovery, you have no business being on a mountain peak.

ABSOLUTE worst case, if you were completely unprepared and have no back-up plan , you can create new tool/armor/weapons to get back for recovery.

Or you can quit. We are all ok with that.

*Edit : I spoke for for everyone , I'm sorry , I meant to say "I" am ok with that.
