That's a tricky one to answer. On one hand the name could have that biting, derogatory sound that stems from feelings of disdain. On the other hand the name could have that impactful, fear inducing sound that stems from feelings of dread. You will find both of those feelings in war. On yet another hand we have the the fact that this is an entertainment property so the name could have a certain cool factor. Each of the various entries tend to slant more toward one of those three than the others. All three sources are a valid place to come at this from.
