>Doctors are bad because their existence incentivizes people to take risks they might shy away from if there were no doctors.

Wrong take. Doctor exist to analyze patient and disease that are unintentional act.

And I don't think people take risk because there are doctors as the risks are on themselves and they have to pay from their pocket...so they won't likely put themselves on danger because Doctor exist for that.

While those migrants take the route because they know they either make it or there would be rescuer that will save them.
