Lest say a kuros actually fell in love with another dragon, and he knew it was bad, and he wanted to seek help in removing these feelings, would other kuros help him, or would he be banished/killed without mercy?

If a Kuros realizes they have that kind of love growing in them, they can pray to Mahoura to help give them strength. But She won’t magically remove it, it’ll be like a challenge She’d give them. If they dedicate themselves to the people, try everything in their power to move past the feeling and cleanse it themselves, she’ll bless them in some way. The ones that allow themselves to succumb are the ones that failed her, failed their people, and deserve the ultimate punishment for it. Kuros view love as a poisonous weakness, if a dragon is weak enough to bend to it’s will so easily, death by their claws, Breithonakt’s, or the outside world is what they deserve. At least, that’s how they view it in their culture :>
