If you forcibly administer an injection of glucagon to a non-consenting diabetic patient, what legal charge is most applicable?

Administering an injection of glucagon to a non-consenting diabetic patient falls under the legal definition of battery. Battery involves intentionally causing physical harm or offensive contact to another person without their consent. In this case, forcibly giving an injection constitutes physical contact that the patient has not agreed to. The act is careless regarding the patient's autonomy and choice, leading to potential harm, emotional distress, or fear.

Negligence typically involves a failure to provide appropriate care that results in harm, but in this scenario, the action is intentional rather than a failure to act responsibly. Assault relates to causing a person to fear imminent harm or offensive contact, which doesn't directly apply when the actual harmful action has been carried out. Fraud involves deceit or misrepresentation for personal gain, which is not pertinent in this situation where consent is the primary issue. Therefore, the most relevant legal charge in this context is committing battery, as it directly addresses the lack of consent and the act of administering the injection.
