This discussion of MC's last interaction with Rachel--the aborted spanking--just won't go away, so, fuck it, I'm jumping in.
Thing is, I LOVED that interaction; it is one of my favorite scenes in a game full of great scenes. It was moving, powerful, and I'll even use the word poignant. And in part, that is because, yes, it aroused my sympathy for Rachel to some degree; I could see it hurt her. I did not feel triumphant about it, "yeah, bitch, you got what you deserved." My feelings were more complex: this is just what she needs to actually reevaluate her life and start turning herself around.
So I've been thinking about it. Imagine that the individual who hated that scene is NOT trolling. Then why such a drastically different reaction than I had to it?
Here is a hypothesis: suppose you, or a loved one, had been treated in exactly that way. Suppose you or a loved one had to deal with being emotionally abused the way Lucy was physically abused. You might, then, look at that scene and be horrified.
It is very difficult for us humans to see something that evokes powerful empathy, reminding us of traumatic experiences, and say, "Well, but that is MY issue. This is not an inherently evil thing, I am reacting based on my personal history, not to what is actually there." I know that I have a lot of trouble separating things like that; I can't reliably do it.
I think the scene as it played out is perfect and I am eager to see the results of it. But I can also sympathize with someone who, for personal reasons, sees it as just too much of the wrong thing.
Anyway, just a hypothesis.
