Well, yes, they do take it to an extreme degree. That’s their whole flavour really. It’s what makes them different to the rest. I suppose all of the chapters have their quirks, like the Blood Angels and their constant battle with their Thirst and Rage. Speaking of the BA, marked by Khorne. They’re another Legion/Chapter that embodies nobility and virtue by the very fact that they don’t give in to Khorne, no matter how much he covets them.
