not only, in most countries operating as a physician requires a license to operate. It can be revoked if the professional violates the terms of the license.

If software had such a thing, it would be possible to achieve something similar. It is not the oath per se that keeps doctors on the righteous path, it is just as much the treath of not loosing your job - but having your professional status revoked (i.e. permamently loosing the ability to work).

On the other hand, reviewing code every now and then, it would be good if you could revoke programming privileges for ever for certain individuals.
