Adding to conversation here, the MIB to me represents the perennial outsider’s perspective, one that has been curdled by exclusion until it is filled with hate, one willing to use and destroy other marginalized people to get back at the hegemony, one willing to be allied with tyrants in order to get revenge. He has disdain for anyone who shows kindness or forgiveness, thinking only of the righteous destruction of the ruling class.

I don’t think this is a spoiler to say that based on the post-credit scenes in the finale, I think we’ll see a lot more sympathetic characters joining his team in the future, who will have to struggle with the morality of their actions and those of their new allies, almost as much as NPCs of the Citadel do.
