I suppose it would depend on whether it was one of his good or bad days. On a good day sure, I figure he would probably have had major concerns about pretty much buying children that he would have been liable to see his own daughters in, but on a day when his mind was slipping and he could barely remember his own name, much less that he had a family?
That's one of the main reasons I enjoy Gascoigne so much: he's a family man with a wife and two children, and is even (unconfirmed but strongly implied) partnered and friends with his father-in-law and fellow Hunter, but with a sickness of the mind that makes him forget all of that, leaving him with nothing but emptiness and bloodlust. It's so impactful when you realize the significance of his reaction to the music box, how the memory of what he's done pains him to the point of him desperately trying to forget.
But yeah, Father Gascoigne was probably never all that interested in the Healing Church as anything but a failed means to treat his deteriorating mind. I also realize on a second perusal that Adelicia is supposed to have been bought [i]after[/I] the Night of the Blood Moon and the schism in the church, so it couldn't possibly have been him since he was dead by then.
