Generally, a tendency for a type of animal to eat its young correlates to a strategy of producing a lot of them. Rabbits, for instance. I'm blanking on the name of it but this is one of a pair of strategies where the other is to be long-lived - like humans, or at the extreme end, the greenland shark, which has a very low metabolism. That's the alternate way of persisting as a species: do nothing, and especially don't die.
