In medical ethics classes it is hammered home over and over again about it doesn't matter who the person is, what they have done, it is you job as a doctor to preserve life to the best of your ability. In a situation like this where the doctors might be fully aware of who this person is and being a doctor in boston an emotional connection to all that has happened they were able to do their job
Seems to fly in the face of the god complex that doctors have.
