She never liked Caroline Mathilde, and as for her children, she saw them as a threat towards her own son, the hereditary prince Frederik and his chances to become king. In Frederik's case of course, since he was the heir to the throne after Christian VII. As for Louise Augusta, she always refered to her as "La petite Struensee", and by saying that we can clearly see, that even though Christian VII accepted Louisa as his daughter, Juliane never her saw as anything else but the bastard child of Caroline and Struensee. I'm certain it would have killed Juliane, if she had lived to see her grandson Christian (VIII) marry Louise's daughter, Caroline Amalie, and thus making Struensee's granddaughter Queen of Denmark.
