Here's the thing, Predator's taint? it's not Nightmare. It only pings a fear check when you get surprised by an unexpected vampire, that's the only actual situation where the beast can seize control over you and force your into a fight or flight response outside of an actual Frenzy check. Predator's taint doesn't make you unaware of your actual combat ability, and in this case, both of the BP 1 vamps are excellent warriors, as other combat threads have shown.
Asa had to deal with neonates mouthing off all the time. At one point there was even a torpor closet for them and it got added to every court. Eventually it got so bad that he made the "don't talk to me unless i want you to talk to me" law so he wouldn't have to deal with mouthy neonates, and they still mouthed off to people. I'm arguing that this is how vampire society IS, and that in a room with four alpha personalities like this, when they aren't on the same page and neither side is interested in backing down, this is what ends up happening.
If blood potency alone was enough to cow younger vampires, then vampire society would be an entirely different beast. But elders are constantly worried that the younger generations are going to overthrow them and suck out their hearts. That's why they keep the neonates under their thumbs so much.
