Episodes like these can really get on my nerves. Even before the episode started, all I had to do was read the blurb about them finding someone who committed crimes against humanity to predict how the show was going to go: it would be an episode about a guy everyone thought was evil when, just perhaps, he really wasn't. And that, perhaps, what is evil is just a matter of perspective. Well, maybe in some cases it is, but perspective is not all there is to making moral judgments. There is moral agreement among cultures, and some people are just plain evil or don't wrestle with the consequences of their actions (i.e. sociopaths). Not everyone can be "redeemed," and more often than not, occurances that appear evil don't turn out to be "misunderstandings." This recurring suggestion in works of fiction that nearly everything is relative is erroneous. Taking this "embrace the gray moral relativism" message hammering may be a nice sentiment, but it isn't true to life.
