I did watch it all the way through without pausing, but I think that, if anything, it makes me a worse person than you are. Or not worse, really, but it's slightly disturbing nonetheless.
I watched Irréversible at the theatre and I almost walked out of that, but that's the closest I ever got while watching a movie. When I watched Earthlings, however, I did pause it and go out to play with the dogs and hug them for a good long time; and never went back to it. But I think that doesn't count, it being a documentary.
