Our Sinners are great teachers...for better and worse (Spoilers for New ID)
In the main universe, our Sinners teach Jia Xichun and she becomes a goddamn monster ready to be the Hierarch of H Corp within a month.
In the HOS Mirror Universe, they were so good at being bad parents, they accomplished the goal of turning Ryoshu into a living Concept Landfill.
What this tells me is that our Sinners are awesome at teaching people...both in the good way and bad way.
