Chris Hayes dumbfounded as Trump exposes himself as a 'sociopath' for all to see

President Donald Trump just revealed himself as a "sociopath" for the world to see, according to MS NOW's Chris Hayes.

Hayes opened his show, "All In," on Thursday with a blistering message to viewers.

"Everyone once in a while, you just have to remind yourself the president of the United States is a sociopath. Or, at the very least, being charitable here, he just can't help himself from acting like one. "

Hayes then catalogued what he called a series of genuinely shocking moments from Trump's Oval Office appearance earlier in the day.

The host zeroed in on Trump's jaw-dropping exchange with a reporter who asked why U.S. allies weren't notified before the Iran strike.

"Donald Trump's sociopathic behavior, his inability to show any tact or decency or just appreciation that there's other human beings in the room with him who also have inner lives, emotions, right? It was on full display as he hosted the prime minister of Japan in the Oval Office today and gave this genuinely shocking answer to a Japanese reporter's perfectly legitimate question about coordination or lack thereof with allies during this war."

Trump responded by cracking a joke about Pearl Harbor to the face of Japan's sitting prime minister, Sanae Takaichi.

"Who knows better about surprise than Japan?" Trump said, as Takaichi looked visibly uncomfortable. "Why didn't you tell me about Pearl Harbor? Ok? Right?"

Hayes, like everyone in the room with Trump, was barely able to contain his disbelief.

"That's the guy. That's the person managing the war, who has this unfathomable power over life and death. That guy is going to decide who lives and who dies. He's arguably the most powerful person in the world.

Japan is the only nation on earth to have suffered atomic bombings — attacks carried out by the United States — and Trump proceeded to hint at nuclear weapons capability while the Japanese prime minister sat beside him. Seems to be a flat out sociopath and a narcissist," Hayes railed.

And if that "gross, weird, awful answer," wasn't enough for skeptics, said Hayes, there was also his bizarre gleeful disclosure, on camera, of a Republican congressman's undisclosed terminal diagnosis.

Hayes played a clip of Trump crowing about the revelation while slapping House Speaker Mike Johnson on the back.

After 11 years covering Trump, Hayes said he keeps trying to find new ways to say the same thing.

"About how just wildly dangerous it is to have a likely sociopath as the most powerful person in the world leading this country at this point, into this war of choice with no end in sight, putting Americans and people all over the world in danger. Killing people! He's going to decide who lives and dies. That guy!"
