What can Space Marine Chapters get away with regarding the way they operate?
Founding Legions I know usually can get away with most stuff because they simply got prestige and other narrative excuses but what about Successor Chapters?
At what point would they get "negative" attention from any other Imperial factions from the way they conduct stuff, like as long as you don't act like mass-murdering psychopaths, worship not-chaos idols, not aggravate any Chapter you come across etc will you just not get scrutinized and draw the eye of Imperial institutes or do Successors need to watch any action they do in the fear of being persecuted and not get sniped to near-extinction like the Celestial Lions?
Any good examples of this in the lore at all?
