Watching Anna—or rather, Juliana—fall into confusion, John did not urge her. He simply stood there and quietly waited for her answer.
In fact, he had not made this suggestion on a whim. It was a decision reached after careful consideration.
First, if he insisted on keeping Anna, John would indeed gain an SSR Tier character with tremendous potential, while also perfectly fulfilling Laiya's request.
But beyond those two benefits, there would be no further gains.

Furthermore, if Anna returned to the Binote Family, the Valdren Family would certainly not sit by and do nothing in order to prevent the Empire from discovering the Child of Light creation plan.
