I kind of phased that out in the development process. Now having a high morale doesn't really achieve you anything during the story, but does put you towards a couple of different endings which depends on high morale. Only choice related scenes alter your morale, so if you want to get it as low as possible for an ending with Chloe as a slut, I'd choose the obvious choice to get her into lewd situations.
As for the walkthrough, that is going to be updated with the next patch. I keep intending on doing, but most people tend to what more of the game than me spending time with a walkthrough.
