Prolonging suffering is unethical
Ending patient’s suffering is more ethically justified than prolonging it.
Self-determination is a human right; patients have a right to a quick and painless suicide assisted by a doctor.
Article 6.1 of the International Covenant on Civil and Political Rights approved by the United Nations states, that "every human being has the inherent right to life. This right shall be protected by law. No one shall be arbitrarily deprived of his life". Proponents of legal euthanasia argue, that the human right to life should also include a one's right to die with dignity and the refusal to grant it violates the freedom of an individual.
Humans have an innate right to life. Such right includes a right to self-determination, autonomy, and dignity. Denying an individual an access to legal euthanasia in case of painful, terminal illness constitutes a violation of his rights to make autonomous decisions about his well-being. Neither a state, physicians or other people should be able to force a person to go on living against his will.
Various formulations of the right to life do not imply the opposite "right to die" - such interpretation is unfounded and not recognized by the majority of international tribunals and law academics.
Each individual has an innate right to life. This right includes a freedom of making autonomous decisions about his life. Therefore, an individual should have a right to terminate his life in case of incurable, painful illness, since it's an autonomous decision concerning his life.
The right to life is concerned only with an unlawful and arbitral deprivation of life. It does not give a right of choosing death over life to an individual.
