How we cite our quotes: (Part.Paragraph)
Quote #1
"'This brother of yours, he was possessed by the devil.'" (1.63)
The question of what happened to Louis's brother is a question of good vs. evil. Was he seeing visions from God or from Satan? This question is also unanswered, just like Louis's good vs. evil dilemma. Also, if Satan exists, then can evil be attributed to him? Are vampires (or people) evil by nature, or because evil influences them?
Quote #2
"People who cease to believe in God or goodness altogether still believe in the devil. [...] Evil is always possible. And goodness is eternally difficult." (1.67)
Can you have good without evil? If evil is always possible, does that prove the existence of good? And does Louis ever see any good in his long, long life? Is Louis better than Lestat and other vampire precisely because he's so tormented? Goodness is supposed to be difficult, after all.
Quote #3
"'I'd like to meet the devil some night,' [Lestat] said once with a malignant smile. 'I'd chase him from here to the wilds of the Pacific. I am the devil.'" (1.169)
Trying to follow Lestat's circuitous logic, would he be chasing himself? Disregarding these confusing statements, what's evident is that Lestat seems to be evil for evil's sake. He enjoys it. Maybe doing evil acts and enjoying it is what really makes a person evil.
