I guess it all depends on perspective but even with this new Mafia angle I think Leia stands far above everyone else we've seen as a despicable character.
I mean let's be honest how worse could she be? She deals drugs, deals weapons and engages in prostitution. And this is only what we know for sure. There's a chance she actually made someone "disappear". And I'm sure her criminal activities are more vast and nefarious that what we know until now. She's possibly a loan shark too given the shake down we see at the bar. She is so bad that even her lowlife criminal henchmen are concerned about how far she's going. Let that sink in.
Her lowlife criminal trash pals are worried that she's going too far.
Now I know that people playing these games are riddled with "porn brain disease" and that makes them more lenient but imagine for just a minute that she was a real person. In the real world. How would you feel about her?
I have no idea what's coming next in the story but to me, she's already beyond any possible redemption. Prison or morgue is what she has coming to her. Preferably the latter
