Having come from the lands of the Reds, he knew what they were about.
Coercing men and their tribes of warriors into joining their side, only to exist in the shadow of Hospitaller and be spat upon at every chance they could receive. The Hospitaller would employ these men, deep within their lines of fortitude, and exploit their labors to benefit themselves only. When they would war, it would be in their name, not in the combined efforts of all of their faction. However, when men too knowledgeable to follow such tyranny any longer, and continue to be exploited rise up against it--they are labeled an enemy of such state and they too join the ranks of the enemies, without given proper chance to flea the holds of such a tyrannous rule.
This is what the Knights Hospitaller of this day know--How to fill men with false promise, gain allies for exploitation, and then, in the end, they will slaughter their own "allies" and fuck their women and sell children to slavery. Thank the Lord I am sided with the Green now, for I will not be subject to such foul treachery any longer.
So since it's all roleplay, you can't fault me for pointing out what Hospitallers are actually doing to their comrades.
