This episode is awesome. On a sub text level, it spells out the lure of not living by rules. The freedom and fun. It also highlights the dangers of not 
living by the rules. That said, it's also an amazing episode from a Faith point of view. There's a few parts where Faith is the same person we met in Faith, Hope and Trick. Her false bravado is still very much present. At the end of the episode, where Faith says she doesn't care, nothing could be farther from the truth. The fact that she cares so much is what pushes her over the edge. It has her resorting to major justification and massive think-throughs at every level. The truly tragic part of the whole 'Faith' arc is, that she needn't have gone through what she does, if Buffy hadn't droned on. We have Giles defending her position in Consequences. Although he's far more eloquent than Faith, he says the same thing about innocent bystanders.
Her love of slaying is still there, as is her sense of fun. What's new is the fact that Faith doesn't seem intimidated by Buffy. She's the 'leader' in this episode. She's teaching Buffy about the rules of slaying. As stated before, Buffy is the exception to the Slayer rule. Buffy really gets lost in Faith's world for a while, although not 100%. She's forever making sure she doesn't overstep the mark. She'll steal the weapons, but her concern and panic is still there about the police. Again, that's probably the one major difference between Buffy and Faith.
Buffy has people who not only care for her now, but she was brought up in a loving environment. Faith comes from a background where she was neglected, used and let down. So, concern over the general populace doesn't rate high on her list. This is the paradox of Faith though. Pre-Revelations Faith cared. Even in Revelations she was worried that Angel 
"could kill a whole mess of people", even at her worst, buried deep down, she cares.
Getting back to Bad Girls, Faith's not about to listen to Wesley, courtesy of Post. Her former respect or deference for Giles has also gone out the window. It was still intact in The Zeppo. Speaking of which, again I feel the need to point out that Faith doesn't really seem to subscribe to 'get some-get gone' as she really does seem to like Xander. She really was making sure Buffy had no romantic feelings for Xander in Bad Girls. As pointed out in the episode rundown--a new aspect in this episode, is the fact that Faith doesn't listen to Buffy. Buffy listens to Faith. Yes, anyone can point to Faith, Hope and Trick and say she didn't really listen to Buffy the first time they slayed together. But that was different. Faith was exorcising her personal demons no pun there. When crunch time comes, Faith will defer. But not this episode. This episode really does set up the fact that Faith lives by her own rules after Post. Once again, establishing what a pivotal episode Revelations was.
Faith clearly loves her life in this episode. While Buffy is slogging it out in school, obviously, Faith patrols. Again, (although unseen) that fact is actually sad. It highlights once more, that Faith is nothing if she's not a Slayer. Also, not confusing her false bravado with 'love of slaying', Faith appears confident and happy with her lot. What many see as reckless, Faith sees as fun (much like her jumping of the highest point in the quarry - see Graduation Day 1). She never had anyone telling her what she could or couldn't do. Hence, in a very real way, Faith doesn't see danger the way others would. She sees challenges or excitement. Also, on another sad note, Faith has such a low opinion of herself, that she probably figures no one will miss her if she died anyway (obviously this changes later).
Faith relishes that fact that Buffy seems to look up to her. She doesn't really acknowledge a crushed Willow when she comes by Buffy's to pick her up for a night's slayage. She has to feel great, that for once, the inseparable bonds of friendship between Buffy and Willow seem to have, actually separated! In Faith's eyes (and Willow's, not to mention the viewer) Buffy has abandoned Willow for Faith. For someone so neglected in the past, Faith feels on top of the world. Also, as Buffy alludes to, Faith and herself are really the only ones who can share how the other is feeling. And that's powerful.
Once we arrive at the death of Alan, both girls (obviously) panic, but it's interesting to note that many viewers forgot that Faith returned to the scene and did feel remorse. I know it bothered me that I had to remind Buffy fans. Clearly, it must've bothered Eliza on some scale too.
Eliza loves the Faith character, so she did go out of her way to remind people that Faith did go back and did feel remorse. However, after a "lifetime of practice" of looking after herself, Faith's self preservation kicked in, and we learn that she's dumped the body. She'll later justify everything with a blanket comment that "the guy was up to no good anyway". The beginning of her denial stage, however, starts with the comment to Buffy of: "I don't care". It's all downhill from there.
