That's the thing though. Both Faith and Dana are killers.
Who other than Faith would have empathy with Dana, and possibly be able to connect with her. Plus Faith has that whole redemption thing to pass on, that she got from Angel.
On the other hand it's nice to think of Faith finally happy, and with Wood. I wonder if Faith could ever do that wife of the Principal trip?
Oh, but wait...what's this thread about again? Oh yeah, should Faith go to jail? Nah I don't think she should turn herself in again.
I didn't want Bufffy to turn herself in either, even if it had turned out the real Katrina had taken friendly fire the way Buffy thought.
