Quote #4
"She said, 'Get thee behind me, Satan.'" (1.287)
Babette Freniere is not talking about a White Stripes album; she's calling Louis Satan. As if Louis weren't already conflicted enough, now he has a woman whom he loves and trusts call him a devil—and she really believes it. Because he takes his religion seriously, Louis will never get over this, later saying "I don't know whether I come from the devil or not! I don't know what I am!" (1.302).
Quote #5
"The question pounded in me: Am I damned? If so, why do I feel such pity for [mortal Claudia], for her gaunt face? [...] I felt, yes, damned and this is hell, and in that instant I had bent down and driven hard into her soft, small neck." (1.321, 1.322)
After being called Satan, Louis gives in to his evil side. We don't think he would have killed young Claudia if he were not having such a moral crisis.
Quote #6
"'Evil is a point of view,' Lestat whispered now." (1.382)
It's all about perspective. From Lestat's (essentially evil) perspective, Louis isn't being evil. But from Babette's perspective, vampires are evil, fair and square, and no matter what Louis or Lestat think about the matter, Louis's actions are evil.
