Not trying to say that the characters are limited to any emotion, because playing a 1-dimensional character that explodes at anything that gets their goat would be boring. On the other side of that coin, it seems like the way things are now, they nearly never give into anger, or at the least they tend toward the side of restraint. The angel type Azrael is playing isn't a protector, it's a scourge. That in addition to having the ability to use an Oath of Vengeance is a big deal, and should at least reflect a bit more in their characters, in my opinion. Paladins have codes they are to follow by RAW.
For Berg, I don't mean to suggest he ought to be blindly lashing out at people, but it seems he falls into a neutral if not submissive role the majority of the time. Combined with being used as a slave in the past, and the particular path he chose as a character, I feel the hotheadedness should be at least somewhat prevalent when certain scenarios come up.
All I'm suggesting is maybe it would be more realistic, since being prideful doesn't mean being wise enough to walk away, if the characters didn't accept getting treated like trash most of the time.
