While I am a strong exponent of individual freedom, I think people should be to some extent protected from making decisions which are against their own interest, especially when their decisions are permanent and pathologically affected. In some cases, I think it can be rightly determined death is in someone's interest, such as incurable suffering. Anxiety and depression, while often severely painful, are frequently possible to recover from. We tend to euthanize animals when we can't justify the expenditure of treating them. We generally view fellow humans as having an inherent right to our best efforts to help them, rather than in terms of their value to us.
