Nobody is stronger, nobody is weaker than someone who came back.
There is nothing you can do to such a person because whatever you could do is less than what has already been done to him. We have already paid the price. Those who die or quit early and easy and with every good reason are preferred because they are understandable and human. Failure and well-disguised cowardice are more human and more beloved. The consciousness of being deemed dead, is next to the presumable unpleasantness of being so in reality.
