autonomy—the right of patients to make decisions about their own bodies and medical treatments. This
principle is enshrined in the legal concept of informed consent. Informed consent requires healthcare
providers to disclose all relevant information about the risks, benefits, and alternatives to a medical
treatment or procedure, allowing patients to make informed decisions.However, challenges arise when
patients are not fully capable of making informed decisions (e.g., due to age, mental illness, or language
barriers). In such cases, ethical dilemmas can arise regarding whether a third party (e.g., a parent or
guardian) should make the decision on the patient’s behalf, and whether the legal framework supports such
decisions.#### 2.2 **End-of-Life Decisions and Euthanasia**End-of-life care, particularly decisions
regarding euthanasia, brings about significant ethical and legal debates. While some argue that
