I'd say that, as a whole, Summer wouldn't give a fuck. Everything has its predators, mortals included, and the Black Court are just one more...but on the other hand, sometimes species die, and the Black Court have failed to adapt to a changing environment, so they're on the way out anyway.
As an individual, your character can believe whatever he wishes, and given Titania's and all of Summer's belief in 'the wisdom of the heart' and going with your gut, the Court's pretty likely to back the Knight's choice to a fairly strong degree.
