Are you sure you're talking about the right oath?
> [...] Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly I will not give to a woman a pessary to cause abortion. But I will keep pure and holy both my life and my art. [...]
Doctors aren't even made to swear to this oath. They can if they want to, or another oath if they please, or no oath at all as far as I know.
