I think it would be impossible for Light to write down the names of all the evil people of the world. There's around 6.75 billion people in the world, and, lets say, 1/2 of 1 percent of the worlds people are criminals, murderers, rapist, child molesters, and other criminals of that order. You would have to write down something like 35 million name, which is an insane amount to write, and even if you just wrote down 1 percent of 35 million that would still be 350,000. Not only that but he is only going by the people that are reported on the news and who are on the computer database. That's not even taking into account the thousands upon thousands of crimes that go unreported or unsolved. Aside from all that the episode was ok for mainly being a recap episode. If you haven't seen all of the first 25 episodes than its worth watching, if you have seen all the episodes so far then go ahead and skip to the 13:00 minute mark.
