I wonder if Solomon and his party already knew about black rukh and deprevity at that point.

It would be interesting if the two you mentioned would fall into depravity from cursing their fate, but neither they nor their comrades knew that they had actually fallen, since they don't know the meaning of the black rukh. And they only noticed that it was something really bad as the two began to be more and more radical and ruthless as a result of their corruption.
