If Dawn defeated whoever came to Batara's defense, the Awakened Council would study the Horseman's strategies and apply them in the eventuality that a conflict with the Master's Organization ever arose.
If the hybrids defeated her, instead, the Awakened would still have records of the Eldritches' most powerful spells and research a way to neutralize them. Either way, the Awakened Council had a lot to learn from the conflict and nothing to lose.
The only wrinkle in that situation was that even though the Organization was still in probation, they were members of the Council. If Dawn proved to be an overwhelming threat, the Master might have requested assistance and the Awakened Council would be forced to deliver it.
It would have been a shame to miss the show, but intervening would have also earned Bytra's favor with the first responders, and maybe even the services of the Fourth Ruler of the Flames.
