Not to mention, there's such a thing as righteous anger- which is a very useful concept because things get done. If people don't feel strongly about it (and angry in some cases), they won't do it. This is just one of my issues with the Jedi having all anger=Dark Side. One of my favorite book's climax depends on the MC getting angry enough to save someone that no one else could have- and yet it isn't bad or dark. It just is. As for the current discussion: I don't write crossovers. I find trying to keep everything in character and believable to be too much work when I have other stories to focus on. AUs are hard enough!
