on the other hand, the movie's not just about the mechanics and fact of revenge killings, it's about what they ultimately accomplish, if anything, and in order to get that point across to the viewing public, a little dramatic license is in order. Conflicted hitman plays a lot better than sure-he's-doing-the-right-thing hitman. And for what it's worth, one of the people I saw it with didn't think he really came off that conflicted.
