A good question is what happens if the forces of Chaos takes over the Warhammer World?
What would happen if all taint of Chaos would be destroyed?
Which of em, is better for who? And what would "The Greater Good" be?
Many times it is idealist fighting for what they see as a good thing, though it may just be a twisted and screwed up thing...
Another thing is, that if a man sacrifises himself, to save his nation, what will he be saving? A bunch of people, who will use their entire lifes talking about how to make weed taste like cheese, or perhaps just commen thieves and bandits living in the cities/lands that they protect?
It isn't really a commen goal which is good, but the individuals who are, often some psychos joins armies just cause hey, then they get to shoot a weapon- while some of their brother in arms belive to fight for their homeland- which they see as Paradice--- which just happens to be nothing unique really....
The world is how every person choses to see it, and it is hard to say what is good, and what is bad, as most have a different oppinion.
