The Outcasts are not gonna cut off their shipments to their largest market without good reason, and if a few Outcasts do not respect their hosts while in Liberty I think the Dons would view it as more foolish than political treason... it is not like the Rogues are actively hunting and killing Outcasts, only the ones that get out of line. When you go to someone's house you have to show some respect while you are there... if the guys back up on Malta heard you blew up, ask the Rogues about it and find out it was because of something foolish you did in Liberty, I doubt they would hold a grudge against the Rogues.
