I like to think of it that when out of battle, they are just bored... completely and utterly bored due to a lack of any real stimulation. Impassive even. Then when they enter battle, or some other situation that can tickle their senses, they throw themselves into it as loudly as possible to make the stimulation last as long as possible. Completely rational, just loud and devoted to stimulation when they can feel something.

I understand the Bezerkers and Bloodletters but... the Rhino?

How did Khârn do in a monolith? I don't have my codex on me but isn't the highest armour penetration he can get on a monolith is 12? Whilst the AR of a mono is 14, and the special rules of the mono deny Khârn his extra armour penetration dice

I came up against Khârn once, he killed 2-3 of his own guys and as such, the owner of Khârn was trying to kill him by making a building collapse on Khârn...
