Brain-dead victims: suffer or pull the plug?

[Nautilus]

If they are brain dead, then they are dead.They are not alive anymore, the only difference is that the body still works, but in the same way as a machine, where it does what it is supossed to do, but has no counciosness of it.

Now when you are about to die is a different topic.I would say you can just pull the plug with the concent of the person who is dieng.Otherwise is wrong, even if he is in great suffering.
