I don't think Sooraj knows things in detail about all the illegal things hyar doing.
It's just that he obeys them but he knows what is right and wrong but out of his loyalty or gratitude that he doesn't question them or feel that it's necessary.
Hyar making all the plans alone and Sooraj not involved in their evil plans but he seen only when they giving him directions what to do.
So in a way since he not involved in their evil plans and not enjoying the end result like money or other luxury.
We can't say that it's a sin he doing in full sense but he is sharing the sins hyar doing.
There is something that blocking him thinking straight may be after effect of wrong medication used on him.
Once he starts to believe Chakor,things will be clear for him.
About girl trafficking, I still hopeful of a positive twist and they stopped that part suddenly and not reopened so far,in fact that was first issue after leap so when they open it again,there is more to it and Sukor equation will be good that time I guess.
