Barry realized that these Angels and Demons are indeed at the pinnacle of power in this multiverse. They are not afraid to face those monsters; they are only afraid of the mind corruption. Something they cannot kill with their power.
Now that they are free from the possibility of mind corruption, there is nothing else they fear. They stood up from their seats. Their faces appeared calm, even some of them displayed grins that looked like someone preparing to do something they enjoy.
These high-ranking Angels and Demons are warriors. They are leaders of legions containing thousands of Angels and Demons. So their power is beyond doubt. Even though their army is now scattered in unknown places or may have already turned into corpses, their power has not diminished too much.
