This is awful, and I can't see it getting any better for those poor kittens
a part of me would be glad if they were hit by a car, at least then they won't have to suffer the kind of life they're likely to have with those horrible people
Could you take the mother to be spayed and then leave her with a friend/relative to recover so that the neighbours don't see her? Once she's healed I doubt your neighbours will be any the wiser to it
