Yes, abandoning Yustissa to her fate while there's still a chance of victory is definitely less heroic than Bree's earlier choice.  She'll always be able to picture the paladin as they found her, even though - this "time" - they aren't going to find her like that at all.  And the others too - Samedi & Kayerie will presumably jump into impossible odds and be dealt with.<br/><br/>I'm not sure what they will have seen about Aleria's fate with the original route - if anything, I think Bremorel might be impressed by Aleria's stubborn bravery, accepting her fate heroically and refusing to go along with her evil captors... it puts the wizard in a flattering light, in contrast to what the half-elf thinks of her own actions and their consequences.  Interesting.
