I mean, I do believe that even someone convicted of human trafficking is capable of genuine rehabilitation and reintegrating into society but if he's not out there putting in hard work both into himself personally and in victim support/human trafficking prevention then I'm not willing to entertain the notion that he has reformed.

He essentially robbed dozens upon dozens of women of their rights, their money, and part of their lives by throwing them into deplorable conditions. I have absolutely nothing to back this up with but my suspicion is that a non-insignificant percentage of the Eastern European women who were working in hotels for a pittance would have turned to sex work to supplement their income. It's hard to imagine that it wouldn't have been an explicit part of the operation, whether by design or by dovetailing the semi-above board side with a more shady parallel operation.

(It's not like the victims would have been eager to come forward about it if they were forced or coerced into sex work. But if you take young women to a foreign country and put them into conditions that are borderline destitution while they work for less than scrupulous hotels and... I mean, the likely outcome is going to be that a large number of them end up in sex work and nobody is going to convince me otherwise - I'm not that naive.)

From what I can tell he was sorta like a middle-man in the whole operation but if you steal years from dozens of people's lives while you directly profit from it then you need to be paying back that debt to society for the rest of your life as far as I'm concerned. At least, if you want to stake a claim to having reformed anyway.
