Well, there's also the matter of practicality. Trying to help an egg hatch can actually be dangerous to the animal inside. It can
be done, but it has a relatively small window of opportunity and requires a bit of know-how. Even then, there's a good chance that in trying to help, you'll actually cause the hatchling to bleed to death.
Regarding Kass's attitude though...sorry Viz, we can't all be John Hammond
