The solution is to forbid the removal of feeding tubes unless it can be shown that such would not hasten the death of someone. No one has the moral right to assisted suicide. It has nothing to do with spousal rights. Spousal rights have no penumbra that includes murder.
What if an individual has a written directive refusing a feeding tube? Should that be illegal?
that is my view also; removal of life support is to be a remedy only in terminal cases, in the terminal stages. Food/hydration would not be removed even then, unless they were useless (i.e. the person's body could no longer physically make use of them) and unnecessarily burdensome to the dying person.
