This oath you’re referring to is the Hippocratic oath, I’m assuming? A non-bnding oath that no licensing board or medical school requires beyond a formality? Doctors are not going to risk their medical license in the form of law-breaking, Especially with the Texas state AG saying they will prosecute

State medical licensing boards usually consider flouting the law to be unprofessional conduct so doctors are really in a bind here. You should direct your ire to the people who created this situation not the ones who are caught in it.
