[Avatar: The Last Airbender] Why wasn't Azula offered the chance to become a better person?

By the time of Sozin's comet, Azula had completely shattered as a person. Everyone had left or "abandoned" her, which took a toll on her mental state. 

Even Iroh, a man who is a believer of redemption and self-improvement, stated that Azula had to be 'put down', because she was crazy. Why didn't he -- or anyone, for that matter -- try to reach out to Azula like what happened with Zuko? Zuko became a MUCH better person, though not without enduring several trials.

It's not like Iroh just took Zuko in and magically changed his entire character into a good person. Iroh saw that Zuko already was a good person at heart and wanted to nurture that side of him. 

Azula on the other hand has never shown a shred of compassion towards anyone and has acted like a psychopath from early childhood. She is just too far gone for him to do anything. Ever her mother thought Azula was a monster.
