I've used Sancho for other games, so I know the things he tends to do. I don't want or need cheats, but I like some of the other things he does. The Joker Mod linked to page one does the basic "here's what you get picking this choice", but not much more.
You can get Darkness without the taboo patch, but it gets darker and more brutal with it - there's a Maddie malicious spanking scene in Ch3, and apparently a much more brutal scene in Ch4, and these aren't triggered unless you have the patch. I've never understood the mindset that enjoys and gets off on that kind of thing in a game, either as a dev or a player, but I know for certain that I'd likely end up in prison if someone of that ilk dated my sister or niece or any woman I know and did such things IRL, because after I beat his weak pussy ass to a pulp, I'd put a 12g round our two through his face.
I think the Psyche reflects how you are playing - it is a result of your choices and I don't think it actually tells you much other than that your playing style is nice, horny or asshole.
