Of course Ye is ultimately responsible for his actions. He earned what is coming to him. He has to be held accountable. And that is happening.
But his mental health issues on top of his regular personality flaws made him the perfect mark for Owens and Kushner.
If would be one thing if they just made him repeat conservative talking points
But they went way further
They filled his head with conspiracy theories, racist nonsense about balck people, got him to be involved in an illegal campaign for president, encouraged him to sabotage his business dealings, and invest in a BS social media platform.
They do not care for dude. They encouraging dude to burn his life down so they can profit off of it. They don't what dude in a good mental state because that might make it more likely he realizes how he is being used. It is disgusting.
