Except they do care, not just the Bael but most Pure-blooded Devils do. Why do you think Zeoticus wanted Rias to marry Riser? To increase the number of Pure-blooded Devils in his family. Why do you think Extinct clans exist, because there are no longer any Pure-blood Devils among them. Being Pure-blood isn't simple about status, it's their very existence. The day there is no Pure-blooded Devils is the day the Devils dies as a species. Why do you think Pure Angels breed between each other? So that Pure Angels continue to exist as well. It's not a matter of whether they care or not, it's their existence as a race.

As i stated in my example, if Monsters were to exist in this world and copulated with every human on the planet, would there be a real human left? No there won't. This is what's at stake, the existence of the Devil. Regardless of what, Pure-blood Devils need to exist so that the Devils can continue as a species.
