Sint tried to summon a god of destruction upon BT, and openly worshipped daimons (their religion's wiki page stated daimons were gods until the very end), and they were protected by the vast majority of realms until it imploded and geopolitical factors made it convenient to turn on them.
The Blood Cult, with its human sacrifices, became an openly accepted entity in a great number of realms, at its peak. It was even Fronen's official religion. The only bad rep it ever really got was for "allying with daimons", which was somewhat true/untrue (and varying degrees through time), very few people made a fuss about the religion murdering people left and right.
Very few, that is, except those who had (again) geopolitical reasons to oppose it. And the same applies to Outer Tilog, I believe.
Truth is, in BM, pretty much anything goes. If it's in your allies' best interests to set aside your misdeeds, they will do so. If you have enemies, they will use absolutely anything they can think of to vilify you, wether you provide them something to vilify or not. The concept of an evil realm thus becomes moot, because you either fall in the very stereotypical and comical psycopath category, or you pretty much because just about your average BM realm.
