This study analyzes the role of euthanasia as a way of guaranteeing a dignified end of life and the legal restrictions that this practice faces in Brazil. The central problem is to understand how legal restrictions on euthanasia impact the search for a dignified end of life and respect for the patient's autonomy? The general objective of this study is to analyze the relationship between the concept of euthanasia, the search for a dignified end of life and the legal restrictions imposed in different social, cultural and legal contexts. The choice of topic is part of the growing discussion about the right to choose for terminally ill patients in countries where euthanasia is legalized, contrasting with the Brazilian scenario, where the practice is criminalized. In this context, the tensions between the patient's autonomy, unbearable suffering and the value of life according to the national legal system will be addressed. The methodology used is qualitative and bibliographic in nature, with the analysis legislation, relevant judicial decisions, and the collection of data on the public and academic perception of euthanasia. Furthermore, legal doctrines dealing with bioethics and the right to life will be presented, with the aim of offering a critical reflection on the dilemmas involved in this debate.
