A dying man saw his kamma?

I include a paragraph of bhante @sujato 's statement from the link above

The problem with bhante Sujato’s statement above is that he equates karma with visible events, such as a car accident. Though the essence of karma is in the mind. It could be seen that someone is slowly dying in bed, but his mind at that time recalled the murders in the past that he had committed and he felt restless/fearful. So the thought when he is about to die becomes a strong bad karma.
