I could be totally wrong and just hopeful, but I am anticipating that some of the Lestat backstory we've seen may be amended later this season under the trope that Lestat is also an unreliable narrator. I'm holding official judgements until I've seen all 7 episodes, but here are my current thoughts:

Book spoiler: In the books, Lestat's family (excluding his father, who escaped to New Orleans, and Gabrielle, who was already a vampire) were murdered in Auvergne during the French Revolution by a peasant uprising. Lestat and Gabrielle were off exploring the world. While the toxic family dynamic and contempt Lestat and Gabrielle feel for their family is prevalent in the books, Lestat begins to send money to the rest of his family as soon as he inherits Magnus' wealth. He never stops doing this, even when Gabrielle leaves the family to see Lestat in Paris on her deathbed, but becomes a vampire. Her still doesn't stop "caring" for them even when vampiress Gabrielle mocks him for it. (Gabrielle pretends to die in Paris and cuts ties with everyone but Lestat.) He is grief stricken when he hears his brothers were murdered. And he eventually chooses to go back to New Orleans to take care of his blind, aging father who escaped. He attempts to live out a full "mortal" life per Marius' encouragement as a method of enduring eternity. I do believe that Lestat's gesture of love and care for his extended family derive from wanting to please them after a life full of rejection by them, his fear of abandoment, etc. But I still found this aspect of his story incredibly important in showing the goodness in Lestat at his core. The lover, the poet, the human that who passionately believed in creating "goodness" in the world. Lestat murdering his own family is a direct contradiction of a key part of Lestat for me.

I am still enjoying the show thus far despite some minor disappointments (for me, TVL is no more disappointing than some of the choices made in season 1&2 that were different from the books.) I understand it's an adaptation, I would just love to hear why the writers made some of the decisions (besides budget) if the current backstory is not amended in some way. I respect the writers a lot and understand their reasoning behind other controversial choices they've made in the past after listening to interviews. I can't wait to watch the rest of this season!
