Right now, with modern medicine and plentiful food, they'll both probably have families. If the strong guy doesn't have a better chance to survive like that, is he really evolutionarily better? How can evolution proceed when everybody is equally likely to survive?
The sickly weak man doesn't have as good as a chance as a strong healthy guy, though. True, he probably does have a small chance, but as long as its a smaller chance than the healthy guy, evolution will continue.
