People talk about the immortals' responsibility a lot in the series. But has anybody wondered what it feels like being an immortal parent?

(Sorry my English isn't very good. I'm Vietnamese.) Well I had a little chat with my friend this morning (he's still on book 2, so there're many things he hasn't known yet).
Me: What do u think is the most painful part of being an immortal parent?
Him: Nothing. They can enfoy their life till the end of day. They don't care much about their kids, do they?
Me: They do care. U didn't see Poseidon saying Percy's his yêu thích son.
Him: Oh, yes! But the others don't, right?
Me: They all care. See, u havent read enough to judge them.
Him: OK. bạn won. But I still hate them, because they've put the kids "in the wild" since they were born.
Me: Thats not their fault. Monsters will start hunting demigods right after their parents claim them. They have to wait until they're ready, don't they?
Him: So why do they give birth to their children?
Me: They have the right to. bạn think they are happy with that? Nah, it's merciless.
Him: Well then, I wish the Fates would mercy on the demigods' soul.
Me: On the demigods', yeah. But Fates hiển thị no mercy on the gods. bạn see, gods are immortal. Their kids are not. They always have to watch their kids get old and die in the end, but they can do nothing about it. Isn't that merciless?

Well, I know this is a pretty long question. But what's your opinion?
