I think surgeons almost have to be arrogant: "Cut into people? When one wrong move could be fatal? Sure no problem!" And also on the cold side emotionally for the same reason. They are cutting into people all day for their job, they do make mistakes as we all do and if you have a ton of empathy or personal sensitivity I would think you'd struggle. I know my sister described this when she was working in a NICU (yes you are working to save the baby when you do procedures, but you feel emotionally like you are torturing them at the same time and it kills you inside if you don't succeed). Surgeons I think have to have that clinical distance to do what they do day in and day out. It's not a normal job in any sense of the word.
