No to just about all of that. In my experience with my husband and with friends who are on the spectrum, it's VERY difficult for them to lie. And rather than appearing well rested and calm the next day, when a stressful event occurs, it generally takes my husband days to "come down" from it. He fixates, almost obsesses. He definitely wouldn't be able to compartmentalize and act like nothing happened. People mistakenly think that Apsies can't feel stuff the way that "normal" people do, but it's not as cut and dry as that. They just process things a little differently. Those on the spectrum definitely have a moral compass; my husband's is stronger than most people I know. They know the difference between right and wrong. They feel grief and fear and sadness and terror and all the things that everyone else feels. Killing 4 people, driving a good distance to hide the bodies, going to work like nothing happened, and then lying to the public, friends, LE, and a television viewing audience shows a deviance and deceptiveness that do NOT exist as any kind of "symptoms" that I am familiar with or have seen.
