Come to think of it, why is the boss squashing them? Is he expecting the killer ko to be tougher, or clever enough to see the attack coming? Or perhaps he expects it to be able to fend him off?
It's a yukkuri witch trial, which basically proves the boss to be trash tier, the witch trial method is usually born from stupidity and malice, which in general is a must for Trash Yukkuris.
It's kinda funny that in the end, the "father" proved to be as bad as the "kid" (if you remember Boss Marisa's kid was quite arrogant and may had done something similar than her father just to become famous in the herd.)

The only problem is, there is no GOOD choice in the matter. It's go off the only clue you have about the murder and kill a few to save the rest, or don't do anything and risk more and more dying.
This seems about the best way you could test the possibility. Best case scenario, killer koreimu fights back and loses, and all the deaths can be blamed on it. Next best, killer koreimu reveals itself and wins, and the rest of the yukkuri know and can deal with it.
