My sister knows a doctor who botched a surgery due to an argument with a junior who wanted to do some step of the surgery. The senior one was not having it at all and just threw the scalpel directly at him. Nothing happened to him because if we start firing doctors for this, we would be missing out on all the surgeries he did successfully.

That's kind of obvious, I didn't think it has to be spelled out.

Here are a bunch more things to make you even more scared.

- Oops! mistakenly left some instrument inside and sewed up the patient - Junior begging to do certain step of the surgery while the anesthesiologist asking them to just get a move on. - Administered a drug to a newborn baby which was supposed to be given to the mother. (My sister's colleague did this with no consequences)
