I feel like there's always a risk of dying during every medical procedure. And I say that as someone thats had a couple procedures, one of them an 8 hour major surgery. One thing goes wrong and I could have died. We just trust that medicine is advanced enough where the risk is minimal enough to not have to worry about it.
With that being said, I think that the majority of deaths that do occur happen as a result of negligence, not bad intent.
I had to get surgery on my knee at 17, and the nurse told me to draw an X on the knee. I'm like

cause at that point I had been coming to the doctor for a couple months and I'm like, don't yall have this in my records?
But apparently doctors can and do forget and operate on the wrong body parts. Due to negligence, not bad intent.
