And unless you can think of any way they could win in that situation, it's a losing battle all the way around. Remember how it said that the Baels have a lot of enemies. The Underworld is full of a bunch of warring factions. They do something stupid like that and they are done for. Again just having them do something like that after all this stuff in the Underworld that has just happened would just be for the sake that people just want another villain that Issei and his friends can curbstomp and make them look good. Unless they are really, really stupid they won't do it. The purists are prideful and stubborn, yet they are logical as well. Doing something like that will just be signing their death warrant and give their enemies an excuse to get rid of them. Like I said, we don't need another Old Satan Faction at this point in the story. If some devils are actually stupid enough to do that, the other logical purists would turn their backs on them. The difference between them and the Old Satan Faction is that they are willing to put their pride aside for reason.

And what weapons and tools could they use to fight monsters like Ajuka and Diehauser? A lot of competitors had king pieces, yet none of them could even defeat Diehauser. Rudiger Rosenkreutz has been in the top ranks for a while. And Zekram Bael even talked about Issei and Sairaorg becoming Satans.

Old Satan Faction: "You're not the true bloodline of the Satans! The true bloodline of the Satans should rule the Underworld!"

Purist Faction: "You're not pureblood devils! Only those of pure devil blood can stand in the Underworld!"

The devils do value strength as well. Why do you think that Issei has become a high-class devil in less than a year. They're just going to have to swallow their pride. There is no possible benefit to them from doing that.
