You chose your "evils". You continuously fought alongside Sint, and betrayed the realm that founded you over a fringe religion having but a handful of followers in it (and even having greater numbers of followers and temples in other realms). Sint worshipped the invaders as gods, tried to summon their "destroyer" god, and unleashed their armies against the other realms of the continent. The Blood Cult did...
Yet it was the greater evil? No, the Blood Cult was a pretext. There were a *lot* of clues that were picked up that Mesh would eventually betray Enweil, it came as a surprise only to those too blinded by the memories of the old days.
Basically all realms engaged in long walks to fight the daimons. Rio did, Enweil did, all according to their abilities and opportunities. Considering this, Mesh did not do any more than anyone else. Hell, considering they had much greater opportunity and capacity to act, they did considerably less than many.
Yes we were allied with Sint for a time but not because we liked them or suddenly forgot what they did during the war. We allied them to fight the Daimons at Jopo's Mouth. It was considered a necessary evil to fighting the Daimons at the time. Given the right opportunity and ability to do so we would have been glad to see Sint get what it deserved despite their supposed repenting of their ways after the 3rd invasion.
Also, considering various individuals within the Blood Cult were part of the Netherworld we did think they were a big threat. We thought the Daimons were using it as a way to gain influence in human realms.
