is, simply put, the same as protecting their own future.To stake one's life to protect one's child...Putting one's self into danger for that reasonis often referred to as selfless love, but...If you think about it, to a parent, a childis a existence so close to them as to almost be a part of them.putting it that way is really just the supreme manifestation of one's own ego.It's nothing so great as selfless love.
