Bael and Zariel's differences were not great.
Zariel was simply too impatient. Before the devils could accumulate greater numbers, she had been blinded by rage and launched a proactive attack.
After all, no matter what, Zariel was a fallen angel. She was not a devil born in Purgatory and had no empathy for the other devils.
Bael, on the other hand, was exactly the opposite. He had fought through countless bloody battles, rising all the way from a Lemure to reach his current position.
He better understood the thoughts of low-ranking devils—even of all devils.
Among the many devil dukes currently in Purgatory's Avernus, virtually none had climbed up from being Lemures.
Zariel was a fallen angel, fallen from the ranks of divine attendant angels.
Many of the other dukes had fallen as well and been transformed into devils.
Unicorns, hawk-faced men, Hellcats—dukes of all kinds.
That was why Bael was more eager to bring the Blood War to an end.
Second:
At the Bronze Citadel, Bael would receive more support from the Spirit Realm, even from the various heavenly realms and different gods.
Huo Ling had deeply experienced this when he had previously been in Bael's military camp.
Huo Ling had visited the territories of many devil nobles. Even in his own territory, there were not many mercenaries. Under an ordinary greater devil, perhaps only one-sixth or even less of their forces were mercenaries.
And even fewer of those mercenaries came from heavenly realms or served gods. There were almost none.
Bael's army, however, was completely different. At least one-third of his great army consisted of mercenaries, and there were even many divine legions.
Bael was a greater devil skilled at drawing upon support from other worlds.
Therefore, Bael would certainly continue to exploit this potential in the future.
