However there is a key distinction between disrespecting a faction's lore, by claiming you are the sole representation of what the entire faction is like (which Aegis isn't doing)
And having your faction, which is a /part/ of that faction, have its own individual roleplay that differs from the norm.
Aegis could very simply be poster boys meant to look a lot better to the rest of Sirius to secure deals with nations, and contractors, while actually being some of the worst criminals to ever live. Or, they could be genuinely good guys who do no wrong. So long as they don't claim that their roleplay, and faction, is the sole truth of what Bounty Hunters all over Sirius are supposed to be. That's fine.
To draw a parallel, my character Hemlocke, leader of the Liberty Rogues, does a lot of things that aren't very rogue-like, and in some circumstances, noble, at the end of the day he is still a piece of human garbage that kills people for fun, but I never claim that Hemlocke is the ideological perfect image for what a rogue is supposed to be. Because he breaks the norm, and isn't a "true" rogue.
Nor do I claim my faction represents the whole of the faction or its lore, because (especially with the rogues) it is not possible one faction defines ALL of the npc faction, it is a representation of itself, until it tries to claim itself as the gold standard and purest representation. Which Aegis has not done.
So while you are right regarding Bounty Hunter lore. That isn't applicable to this circumstance.
