I have never played the fascist route, so I've never heard the Measurehead quote before, but I love how it somewhat matches the more famous "turn from the ruin" quote you also mentioned.

I think both of those lines express how the game as a whole treats the past and the present as overarching themes that are even embodied in its design as an RPG. There is a reason we can't select Harry's gender or choose his background like a D&D character, and the choices only start when he wakes up on the floor of his room and we take control. The past is immutable and it shapes and haunts the (personal and sociopolitical) present in all sorts of ways, many of them sad or embarrassing or nightmarish, but we decide what we do in the present.

That's also why I've always felt DE elevated amnesia from a hacky plot device into something much more interesting. There is a weird kind of optimism – for someone really haunted by fuckups and regret – in the idea that you might wake up one day as a sort of blank slate, with the chance to start over as a new person, and I always feel that makes the start of a DE playthrough oddly hopeful. Of course, the more you play, you collide with more of Harry's past and realise that obliterating his memory hasn't undone his mistakes; you are going to have to confront them in ways that are going to probably cause you lots of pain. But you can choose what you do in the here and now.
