I once thought of ways to write him as a boss. From what little characterization we have of him, it seems he's not sadistic, but rather uncaring and emotionally detached, given from the fact that he gives up on the abuse and instead just ignoring her after realizing she wasn't going to turn out to be the bargaining chip he hoped for. The only potential route for redeeming qualities, IMO, would be in response to Bernadetta's death, and realizing too late that his family is more than just a tool to manipulate for his own ends.
Although, that's just how I would write it, and I prefer humanized villains with plausible motives. Realistically speaking, I think A is how it's going to go down, but I would prefer B, because I think "evil father" is just too static for a minor villain.
