Yeah, because he created Ray as monster by make her drink poison. But then, he is afraid that the fetus inside of her will consumed her and died, because she created a monster which is he knows that the unborn child will be a monster too.
It's not a poison but a potion made from the mixed ingredients such as the lake water,his blood and a feather of a baby white bird. And you're right,he was afraid that the babies will eat their mother. He was a monster himself so he thought that his children might as well be.
Deceiving someone that long and continuing to do so to get rid of the unborn child is just something else
