I just recently posted the first chapter of my latest Fanfic, Downwards Spiral. That will be replacing this story and it is a rewrite of this story in a way.
When I first started Selfish Sacrifice it was me expressing my frustration over the fact that there was no time travel fanfictions where they fail to fix things and end up making it worse. Selfish Sacrifice's whole purpose was to simply be a fanfiction of that variety and to get the idea out there. the problem with that is the dystopian ideal controlled the plot. I made Dumbledore decide Harry was Voldemort for no reason except to make that dystopian ideal a reality; I made him scorned and have no friends again to reinforce the dystopian ideal. The idea that birthed the story controlled it and I became overeager about it and as a result had large time skips between those scenes. When setting up the background for those scenes I copied it directly from the book. Which to be frank is boring, if you wanted to reread the book you would read it not my fanfiction.
As a result of all those time skips my characters had no personalities and it made it near impossible to write once I got to the point in the story where there was no timeskips.
Now onto Downwards Spiral;
Unlike Selfish Sacrifice which revolved around a very cringy romance, this story revolves around Harry with romance as a side factor. The pairing for this story is still undecided although it was Harry/Ginny in the past (Or is it future?) it will most likely be something else in the present. While Harry/Ginny is still my favorite pairing; it is crucial to the plot that they don't end up together so unfortunately he will be paired with someone else. I understand if you don't want to read it because of that I won't change it.
In Downwards Spiral I have no intention of copying directly from the books so I can fully flush out my characters (with the exception of things like the sorting hat song) and I also have no plans to do any huge time skips once he reaches Hogwarts. Dumbledore won't presume things until he has evidence, etc.
While Selfish Sacrifice revolved around the idea of Harry going back for just Ginny, it was meant to be a play on the classical line of "You sacrificed everything for me," that appears in every time travel fanfiction story ever. That line is so dumb; going back in time to save their lives is because he couldn't live without them. Downwards Spiral on the other hand is about Harry doing it for everyone after they were all wiped out. Both story's to adhere to the ripple effect and Murphy's law although Downwards Spiral to a much greater extent. Pretty much every event has been at least slightly changed.
To avoid Harry becoming overpowered too quickly, Harry has his future memories but is still his past self so he has to relearn everything.
I hope you decide to check out Downwards Spiral but I completely understand if you don't. I wish you all the best.
If anyone wants to adopt the original Selfish Sacrifice; or even just know what I had planned PM me and I'll send you the plot outline.
