How about let enemy's public treasury be captured when taking a settlement?

[G. Septimus]

And in EB, the unselfish general will get nightmares from that action
Maybe we should add some public order bonus for unselfish general? so they can doing their job "peacefully?"

hmm....
That's the rule of war. you can't change it ,man. even an unselfish general can't stop doing that. Because, money is everything
A general always wants the best for his troops
