You tell that to everybody with a glioblastoma.
Go ahead, tell them the aggressive mass in their brain, the thing that shortened whatever potential life expectancy they had to, at best, single digit years, isn’t a guaranteed death sentence.
They’ll be so comforted by the idea that maybe their already shortened life expectancy will be further reduced by a car accident or some idiot with a knife.
Perfect example. I myself survived a grade 4 GBMO. "5-year survival rate: 10%, median life expectancy: 18 months." That was 13 years ago next month.
Your idea that hope is going to lead to a car crash? or murder by knife? is one of the most bizarre and ridiculous things I've ever read.
