If people get killed and Q fucking knew it beforehand, it definitely is Q's fault. Why wasn't it prevented? Why did people have to die? If "Watch CA" was referring to the CA wildfires, it's clear as day that Q should have acted or at least tried to evacuate or prevent any people harmed in there.
Yet, this did NOT happen.
People die in a war, correct, but dying in a war is not equal to letting your comrades die when you have all the resources and capacity to save them.
