Exactly! From the article that you linked above:
What did he expect? The public were going by what he told everyone had happened, in those three interviews. His story turned out to be a lie. I understand he doesn't want people to think of him as a monster, but I find it hard to believe that he didn't feel like a monster at any point when he did what he did.
I dug a hole in my back yard once at night in the pouring rain to plant a tree (don't ask, completely good intentions I promise), and even then I couldn't help but feel like a serial killer (LOL!). There's just something criminal-feeling about holding a shovel and digging a hole in the middle of the night in pouring rain, even if it's for a completely innocent act of planting a tree.
I can't even imagine CW not feeling like a monster when he buried SW and their unborn son in a secret grave and dumped his girls in oil tanks like trash.
