I could be in the minority, but I've always seen Trask's treatment of Jamison as pointing to the fact that Trask didn't care who his charges were or where they came from - they all had to comply with his rules or suffer the consequences of his twisted wrath. And I also think that in Trask's mind he sees himself above everyone else by virtue of his perception that he's God representative on Earth - and by extension he's imparted that same sort of belief to his family simply because they are members of his family. Not a particularly Christian attitude to have, Though, sadly, it's one I think we've all seen examples of in real life. I mean, how many religious leaders throughout history have seen themselves not only above their flocks but above nobles and even kings simply by virtue of their belief that they were God's representatives on Earth? Far too many.
