As several other posters noted, CW appeared to feel shame, which doesn't necessarily mean he feels guilty or remorseful, which I believe he doesn't. He felt shame with the spotlight on HIM, not for the good he's done, but for the incredibly, undeniably BAD he's done. I thought if he could, he would have slithered under the table like the snake, he is. CW shed a tear when his Dad read his impact statement, it hit him that his dad no longer can feel proud of him, well, not in public. I echo Frank Rzucek's words, he's an evil monster!
Some insightful observations about shame and guilt.
Guilt:
a feeling of responsibility or remorse for some offense, crime, wrong, etc., whether real or imagined.
Shame:
the painful feeling arising from the consciousness of something dishonorable, improper, ridiculous, etc., done by oneself or another.
Many people who display narcissistic behavior often suffer from profound feelings of shame but have little authentic concern for other people; they don't tend to feel genuinely guilty. The lack of empathy to be found in narcissistic personality disorder makes real guilt unlikely since guilt depends upon the ability to intuit how someone else might feel.
When shame is especially pervasive (what I refer to as core or basic shame), it usually precludes feelings of genuine concern and guilt from developing; the sense of being damaged is so powerful and painful that it crowds out feeling for anyone else. In such cases, idealization often comes into play: other people are then viewed as perfect, the lucky ones who have the ideal shame-free life we crave; powerful envy may be the (unconscious) result. In those cases, we might take pleasure in hurting the person we envy rather than feeling guilty about it.
In others words, core shame reflects early psychological damage that impedes growth; the capacity to feel guilt depends upon that psychological growth and could be seen as emotional progress. If the early environment is "good enough," we develop a reliable sense of self that in turn enables us to view other people as separate and to feel concern for them. Although the experience of guilt is painful, our ability to recognize that our own actions may have hurt someone, to empathize with that person's pain and to feel remorse for having caused it are all signs of emotional health.
