[Thor movies] Isn't Odin really quick to toss Thor out and strip him of his power?

Thor messed up bad.  Asgard doesn't want a war right now.  People are going to die because of his recklessness.  

That being said, kicking out your son (and most powerful weapon) on the eve of major war when you're about to literally pass out. 
 Odin is many millennia old.  He should have known better.  Is he just a super mastermind playing 4d chess, knowing Thor would end up proving himself?  Or did he let his anger and fatigue get to him.

Odin was pretty quick to lock up Hela, too. Loki spent time in prison as well.

Asgardian justice is swift.

But regarding Thor, he was useless to Odin at that point in time. He was too quick to rush into battle, too unconcerned about the potential consequences of his actions, and willing to jeopardize the health and well-being of his peers who went along with him.

Odin can't use someone like that. He surely can't put such a man on the throne.

So a test was required. Either Thor would pass and come back to claim his birthright or he would fail, and Odin would find some other way forward.
