I didn't see the same thing in court others are seeing. I think talk of CW crying, being in fear, feeling shame are all attempts to humanize him. I get why people want to. It's so hard to imagine there are people out there, capable of these types of crimes.
But, CW is not human. He's some sort of subspecies.
This is a man that, one by one, killed his family in a manner that was up close and slow. Then he carried their lifeless bodies to his truck like he was making a dump run. Drove all the way to work with a truck bed full of corpses like it was nothing. Dumped his wife and unborn child in a shallow grave. Making sure they didn't even get to be together in death he carried tiny bodies to two separate tanks and then shoved them in tiny holes, scraping their skin and leaving clumps of hair along the edges.
Then he went off to work where it was reported he was behaving normally. Made a few phone calls to unenroll his kids and sell their family home - a place filled with memories of his family. A place they should have felt most safe. Gave cool as cucumber interviews where he laughingly showed off his favorite tshirt . Casually dropped hints to his friends he and SW were thinking of selling their house.
These are not the actions of a man capable of feeling any shame or empathy. He doesn't even feel fear the same way you and I and I do. I imagine he has a lot of anger and envy, but Chris Watts only cares about Chris Watts. Any emotions shown in court were 100% self serving.
Even DA Rourke said throughout the entire duration of the investigation CW never showed an ounce of remorse and will likely never tell the truth.
Not only will he never tell, but I'll bet he'll keep taking digs at the Rzucek family in the years to come. Like SP enjoys popping up every couple of years to proclaim his innocence and desire to find Laci and Connor's "real" killer, we'll probably hear from CW from time to time how SW really killed those babies or some other form of blame.
