I think it is a far stretch from a Ghost/part of Banri's mind to a being that can literally control the minds of other people to make it busy, and also possessing the ability to change the weather.
And even if he was, he obviously didn't want them to fall asleep. That could have happened even without his actions. Putting all the blame on him would be like blaming a kid for tripping another kid, then hours later the tripped kid falls off a cliff because his ankle was sprained as a result of the first kid's actions.
I'm still in the boat that Ghost Banri is in the right. His life was literally taken away from him. Anyone would be pissed. The show might have been better without him, but the fact that he exists will always be true, so I don't see the point in thinking about it.
