I think Michael was genuinely sorry for killing Fredo, but I agree that this sin was the only one that tortured him. I for one am of the opinion that Fredo SHOULD have been disposed of, Fredo threw family out the window when he betrayed Michael. But still, I believe Michael regretted it and I am of the opinion that the confession scene was a good one.
Apple I understand your feeling that III is inferior to eh first two movies, as many of us do, but I am sure you have sat through much worse movies than GFIII, so whats the big deal with watching it?
