What was the choice Lestat never had?
Before Lestat turned Louis, he gave him a choice — to live a life of sorrow, as Louis was currently doing following the death of his wife, or to become a vampire. That is the choice that Lestat never had. Lestat was living as an actor in Paris when he was kidnapped and forced to become a vampire by the mad vampire, Magnus, who killed himself immediately after making Lestat a vampire.
