Ah, very true. Though one could argue that the "source" of the "Jerid's" blood rivalry could be different in the case of every Jerid.
Man, what a loser Jerid was. "You killed the woman I just met like, 2 days ago, who was a little nice to me and took pity on me because I was her underling who sucked compared to her on the battlefield, and who was a hardened soldier with experience willing to die for her cause. Just to get even, I'll kill your innocent, helpless, uninvolved mother. That'll learn you."
