[Interview with the Vampire] Why does Louis de Pont du Lac still kill humans?

Throughout the novel, Louis is constantly tortured by the murder urges of his vampiric nature, often recounting his struggle throughout his interview. He has long debates about this with other vampires and is disgusted by those that indulge in this.
Initially, Louis even feeds on rats and Lestat mocks him for this.

Why then does Louis continue to murder humans if killing animals is a viable alternative? Is Louis a walking hypocrite for giving in to his bloodlust?

Louis gives into the reality that he is a vampire and requires human blood to survive and live a life worth living (pun intended) pretty early in his journey. What Louis gets hung up on is the lack of compassion his fellow vampires have for their victims, and not just a lack of compassion, pretty much every vampire Louis meets *revels* in killing humans. 

It’s like asking how a meat eater can both be pro-carnivore and anti-animal abuse; yes, we don’t really need meat to survive and it’s not the most moral choice ever considering our abilities, but it’s a more enjoyable and convenient lifestyle so long as we know the animals don’t suffer unduly. Louis is a meat eater - Lestat, Claudia, and Armand are animal abusers.
