If a person attempts suicide, are we violating his autonomy by trying to save him?
In general when someone attempts suicide and fails, we'll provide medical care with the intention of saving this person. However, assuming he made a choice to end his life, on the basis of what do we justify trying to save him?
If someone is unconscious and needs resuscitation, we'd provide that care in general. I think we are supposing that it is a reasonable assumption that this person would like to be saved. However, if we have reason to believe otherwise (say he signed a no-resuscitation notice) then it seems like it'd be a transgression to ignore the wish.
I think we should save a person after an attempted suicide but I'm having trouble finding a grounded justification for it.
