The issue of ethical “limit” in treatments at the ending of life is addressed in this writing, following the debate in the National Committee of Bio­ethics and more recently the media uproar on the case of Alfie Evans. The controversy about the suspension of “heroic treatments” is exam­ined, whether and when they are to be considered “excessive” and “not proportionate” in the patient’s best interest. At the root of the dispute lies a different assessment about the role of the “subjective” (patient’s ) point of view versus the “objective” scientific/medical criteria in identi­fying the suitable “proportionate” treatments. The “ethics of subjectiv­ity” is advocated, as a limit to the invasiveness of the new life sustaining technologies.
