The point of this episode was that these guys started killing each other without talking to each other.
The most impactful bit came from Magath. He started off the episode debating history and righteousness with Jean. I wouldn't say he has the moral high ground, but he does have some world history to base his actions off.
Fast forward to Gabi's confessing that the Paradise Island Devils were all scapegoats for the rest of the world's Eldians so they can act as Good Eldians and deflect all hate towards them. Magath realised that this is something of his doing until this point - If not personally then systemically.
I think where you're wrong MFauli, is that you think that the Scouts killing titans without guilt is the same as scouts killing humans without guilt.
Levi being Levi while missing his bits is quite funny.
The woman in Jean's dream had quite dark hair. On first take I thought he wanted Mikasa's babies.
