To be fair, the beasts and the vine plants were responsible for most, if not all, of the deaths of epic godclads.
Epic godclads could resist the spiritual impact caused by gazing at their divine form, so epic godclads who weren't killed by the vine plants and the beasts survived the unfortunate turn of events.
The only epic godclad that the divine beasts managed to kill was one of the rank 6 nobles that went to subdue them. But the two divine beasts had killed so many mortals and normal godclads that the whole city felt empty.
This many casualties meant that now that the battle had ended, there were very few people that were capable of helping the city recover. So Black Axe coming forward with the lucky few from his gang who were still alive was really appreciated.
No one suspected him of ulterior motives for coming forward to help. Even if they did, they needed his help because the city was short of manpower.
