In this case, you're probably right, but there are definitely spaces between 'live with it' and 'lethal'.

I have multiple sclerosis and at the time of my diagnosis the best treatment available to me in terms of slowing the progression of MS had a risk of triggering a rare brain infection that would kill you. So it was a choice between treatments that didn't work as well but had lower risk and treatments with greater odds of being able to walk/work/not be in horrifying constant pain in 10 years but also a small chance of death.

These decisions can end up being horribly complicated, and they are definitely revealing in terms of your values.
