1. The story is not yet finished and we will not reveal info about unreleased content.
2. From our perspective, Eight is not treated like a "good" person if the player does not choose to do so. Seven gets angry, can push him off, warn him, has to restrain herself from causing bodily injury, and can question him in-depth on his actions. There is also far more story content rewarded to the player if they do not give in. There is no additional narrative other than this or the other option where Seven gives in and does not have time to think about her actions. Whether the characters are seen as "good" or "bad" is entirely up to the reader and their assumptions if they make any. We can't change a readers perspective or feelings, all we do is provide situations that happen and Seven's reaction to it (which is usually based on your choice if it is a strong, divisive issue.)
