Yes, because it creates classes of people on the basis of a vague criterion. The criterion for access to MAID is specific to each person. When assessing the individual's medical condition, the physician determines whether or not that person meets the requirements. Having the diagnosis of the condition is one factor, but not the main one or the most relevant. The question that has to be answered is whether the individual fully understands what they are committing to when they seek MAID.
Creating a second class of people whose natural death is not reasonably foreseeable suggests that these people are not like the others—that they are more vulnerable and require more protection—which is not true.
