I have trouble believing that anyone would be so ignorant of the consequences as to do this, but more horrible things have happened.
That depends on which consequence you're talking about.
I got the feeling she'd done this before and gotten away with it. The practiced ease with which she attempted to condemn the man to death by denying him his medication suggests this is a stunt she's pulled before. This is just the first time anyone made a public issue out of it. I don't think she expected professional or legal repercussions.
As for the patient being harmed, possibly killed, by the denial of his HIV medication, it sounded to me like she WANTED that consequence to befall her patient.
How many gay men has she condemned to death this way?
What harm has she done to immigrants? Her hostility towards the doctor suggests racism on top of homophobia.
