Players tend to get very attached to their characters, one reason you introduce them to the concept of pre rolled ones, both when they're starting out and so that if they mess up, they don't feel it personally if the character dies, hopefully learning something in the process of preparing Plan Bees, or coming up with ad hoc solutions.
Traveller doesn't have Raise Dead, or burning karma points to get out of near fatal, or actually fatal, situations. It does have emergency low berths and technology level fifteen, if not sixteen, medical science.
