Perhaps the spear to the chest did more damage than you assume and he didn't think he was going to survive anyway. We'll have to wait until next season to see, but a grenade at that range, even underwater, will kill a man. I don't care what sort of healing powers the island may bestow, I've yet to see anyone recover from a face full of shrapnel.
