Have you ever been accused of something you didn't do? Are you remorseful? No? Then that's proof of guilt. That's the reasoning you're promoting here.
No, that's NOT his reasoning nor an apt analogy. Trump is guilty. He did exactly what he was charged with doing. He probably believes that it wasn't a crime, and he definitely believes that he should never be convicted of a crime whatever he does, but he knows that he did what he was accused then convicted of doing.
Trump's lack of remorse doesn't stem from innocence. It's a result of being a malignant narcissist. He is incapable of blaming himself or admitting guilt.
It must be even more frustrating for Trump to believe that he was played by Biden and Bragg than that he was guilty and got caught. He's wrong about Biden, but I'm not sure that for Bragg that it's not also partly personal, that is, that Bragg might not have brought these charges against others, but because it was Trump, bring it! Likewise with Letitia James' recent civil victory. She was also accused of campaigning to get Trump. Even if true, I don't have a problem with any of that.
But in Trump's mind, it's a game of chess, and he's just been checkmated. It's a game of wills and power, and his wings were clipped by people he despises and who despise him as well. He's like a thief who realizes that his pocket has been picked.
Did you see the movie Dirty Rotten Scoundrels? It's about con men who get conned by someone they viewed as a mark. That's Trump - the hunter who became the game and was cornered and "tased" publicly. MAGA likes its strongman to be strong, not played by the "woke."
