No. Neither humans nor other animals have an instinct to eat their young. No one has claimed that’s instinctual. I’m saying that humans have killed their young, just like other animals, and humans have instinctual behaviors, just like other animals.

Some animals are psychopathic and kill all their young. Some humans are psychopathic and kill all their kids. It doesn’t mean that’s instinctual behavior.

And when pushed to the extreme, like starvation, some animals will die, and a few will eat their young. Humans will do the same, some will die and a few will eat their kids.
