Also, BS didn't make the deal, but it was implied that he could still control the roses without the deal, although he'd have little power over them as he would effectively only have the [i]rose[/i] part of a [i]blood rose[/i]. If he had made the deal, we wouldn't be in this situation.

Yes, he can partially control them, but it`s very flimsy. If Victoire were in active control of her magic, he could do nothing about it because they are of her creation, thereby, she has much more control about it. He can be an inconvenience at time and probably deter her a bit, but he`ll never control her demon roses completely without her permission.
