I am sorry to hear that he died but what did you expect. Someone else mentioned that if he let you pick him up without a fight, he was already gone. He probably had hypothermia and was too far gone. I would have probably wanted and maybe even tried to help him too, being in that situation, But I would have been wrong to do so. Nature always takes it's course and we should not interfere. I know your heart was leading you and I understand, but it is best to leave be. He was obviously a very immature little guy, probably born late in the year. Without his mama looking out for him he wouldn't last the winter anyway. Your effort wasn't completely in vain, for it shows the true heart of a hunter to those PETA people who are watching.
