I would draw the line when the EEG and MRI shows no brain activity.
I would also draw the line when a relative of mine is terminally ill, and prolonging their life would cause pain and suffering.
Just like it has been done for years.
There must be SOME brain activity just to breath ... to open your eyes ... So what brain activity would you draw the line at
Baby Joseph is on the line of that line with brain activity, and you call for him to be killed. So you're saying that if an innocent baby has brain activity, he should be killed, but if there is no brain activity he's already dead so why bother? And you're against the death penalty for convicted murderers? Your only criteria is that the victim must have brain activity. That's sick.
