In all honesty, I don't think that Rem's issue was specifically that this can be done with titles on Prisoner Mode.
Rather, I think that Rem intends for the final starting Control value for Warden mode to be -4 or -5... and those are both values that you can reduce to 0 with the current Edicts WITHOUT any titles at all. Pick things in just the right order, and you can replicate that scenario on Normal Mode.
Stat Growth is NOT as punishing on Normal Mode as it is on Prisoner Mode, which means that on your very first run, you could, theoretically, turtle up, buy every Edict you'd want, and only THEN move out to do terrible things to the Prison.
Let's not forget that this would, theoretically, allow you to farm every single Accessory in the game before you ever leave the office, and the stat growth is not extreme enough to ensure that most prisoners won't start to fap on the spot with that much Charm build-up.
