Good vs. Evil Quotes in City of Ashes

How we cite our quotes: (Part.Chapter.Paragraph)

Quote #7

"It's better to reign in hell than serve in heaven, etcetra, and so on." (2.13.66)

Jace is mocking one of Valentine's favorite quotes here. (Can you identify it?) Valentine is totally find siding with whatever side gives him more power.

Quote #8

"I'm no friend to demons," [Valentine] said. (2.13.86)

Valentine hasn't technically sided with the demons. He's just using them as pawns in his scheme. Does this make him good, or does it make him even worse than a demon?

Quote #9

"I thought we were all on the same side. I thought it was us against the demon worlds." (2.13.93)

This is how things would be if it were simple, but Valentine has to come in and complicated things, doesn't he? Cue some classic Avril Lavigne.
