Guilty conscience?

"...He has a guilty conscience.
He should. And not just because Peter Strzok texted to his paramour what feels like decades ago that there was "no there there." Anyone with an IQ in the proverbial triple digits has known that for a long time. (How distant it seems, months, years, that Dianne Feinstein was asked about the collusion/conspiracy— pick one — and admitted there was none.)
Mueller, unless he was living on Pluto, knew this. And somewhere, deep down, a part of him, an increasingly significant part, I suspect, must have realized what he was doing was wrong. (Besides his demeanor, this may also explain why he gave up on interviewing Trump.)
This guilty conscience was made manifest in the many questions he claimed he could not or would not answer on the subject of the predicate for his investigation. As the world knows, more and more it is becoming clear that the entire Russia probe was a put-up job. Mueller's awkward answers and body-language responding to the questions about why Joseph Mifsud, the mysterious Maltese "professor" of dubious alliances, was not prosecuted for his multiple lies when so many others were was particularly telling....
I notice that some commenters think I am excusing Mueller's execrable behavior in the past (anthrax case, etc.) by saying he has a guilty conscience. I didn't intend that in the slightest. I never bought the heroic image of Muelller. He is and was a pompous creep who ran over people. But the human mind is a complex animal. Many things happen at once. People like Mueller and Comey think they are good, which makes them all the more dangerous. In the case of Mueller, I suspect something was beginning to impinge on that--call it a guilty conscience or whatever, an uncomfortable truth-and he started to disintegrate in the tradition of the witch in the Wizard of Oz. That's what we saw today...."
