It's interesting to see some people believe that even with the maximum bitchiness and evilness of Monica, they still think that she's actually good in her heart.
I'd say most people in this game are actually terrible people.
There's a roleplay element to it. I played the Decent path and it paid off greatly.
Monica is a blank slate at first. You can go along with the premise of her being a bitch or undermine it by piicking the kinder options. Then it's up to you if she isn't that bad or if she just woke up in a non-bitch mood that day.
For me, It's more about the trip than the destination. I'm doing what I think will get Monica her life back, trying to be as decent as I can.
