 A second challenge to grounding informed consent requirements in autonomy is that violating informed consent requirements can have positive impact on autonomy. One example is when closing off an option, in violation of informed consent, enables more important freedoms. For instance, closing off patients’ options for voluntary euthanasia was said to increase their autonomy by freeing them, as well as similar patients, from family pressure to use that option (Velleman 1992); surely it may do so even when accomplished through forced injection of an antidote or other violations of informed consent.
