Ziggy, not sure where you targeted your nazi-practice-themed question. But i think it is pretty clear that trying to save one's life is not the same as trying to make him immortal. If you ask me if one million people should get hospital beds and access to procedures they need so as to get better from being ill, then i would surely reply positively for all of them.
And if you asked me that one, sole person, gets access to tech which would allow him to live to be 200 years old, etc, i would always say no.
