It is hard to extend morality between species. The idea of parents sacrificing themselves for their children seems to resonate as highly moral, and is also a common pattern in biology. But how it plays out, from humans where the male can provide more by continuing to live and "hunt/protect/teach"-- but at the risk that the "hunt/protect" might end his life, to spiders where (some species) the male gives his body to provide nutrition for the child, well, who am I to say which is more moral?
