[Avatar the Last Airbender] Why did team BoomerAng believe the war would be won if Aang defeated Ozai during the eclipse?

They had no idea that Zuko was turning at that point, and Azula might have been a more devastating leader than Ozai!

The plan was to have Aang defeat the Firelord and capture the castle. They wouldn't have just let Azula take over. 

Fire Nation culture is based on honor. The intention was to use that against Ozai and his followers into forcing him to surrender.
