These are mostly all wrong.

For NIN you say:
NIN: Neutral because they stole, but from the gov't enemies. They obey authority, but only if it helps them. Evil because of high DPS and independence.
The first half I agree with...but being independent and having high DPS doesn't make you evil. They do not kill/assassinate for fun/pleasure. NIN should be lawful evil. They follow a law/honor code of Shinobi, which the NIN from the AF quest disobeyed when he assisted the Empire destroy Doma.
