Khorne was actually about martial valor, if you go waaaaaaaaaaaaay back, but over the years it got changed into Kill!Maim!Burn! . Personally I prefer to go with a more .. controlled bloodlust. The urge to kill is always there, always slowly building. Vent it, and it comes under control again, but while it is being vented, the red rage is in control, and the urge is to kill until nothing remains to kill. Try to keep in in check for too long, and it will break loose on its own anyway.<br/><br/>That's how I characterise my own World Eaters lord character.
