Statistically speaking, if you really caught them when they were about to die, then it should not matter, like picking a pre-corpse. Anyway, in captivity they might not have access to mating and many other "privileges" given by freedom, but they have a much lower chance of being eaten.
I would certainly keep them, and think of myself as a trustee of a national heritage.
