in canada, and in much of europe, we actually allow for assisted suicide, which takes the issue to the next level - we acknowledge there are scenarios where one human is permitted to kill another, if the one being killed makes the request.

i couldn't imagine anybody arguing that killing somebody on request isn't immoral. rather, the argument is that an individual's autonomy is the more important consideration, and if somebody wants to make the immoral choice to end their own life then they have every right to do it, because they own their own body.
