Ouch…but you are right. This route is basically a parade of the worst of Sunohara. One of the key parts though I think is how Sanae shows that normal and otherwise good people can kind of end up on track where they make bad choices - especially to maintain the status quo, but can be led back on path. Sunohara’s greed basically escalates to the point where he turns a blind eye to his sister’s predicament. I kind of wish we had eyes on Sunohara for when he made the clear choice he was more worried about Mei than was invested in Sanae. I kind of feel like he might have been skulking around for some time.
This is very much something you see repeatedly I feel. Tomoya is almost never really self motivated, and in fact is more than willing to do things that he knows people will misunderstand if he thinks it will help someone. And you know that he is aware of what other people think - you see him at times playing up the delinquent image to intimidate people - but he never really goes out of his way to be concerned about it.
