Miscalculation

Foreword

A 20-year-old Harry Potter discovers a type of ancient and obscure magic, a ritual spell capable of sending someone to the past, this spell has been banned by the ministry, and his knowledge is known only to the ancient magicians of that time, currently nobody More knows about this. Harry is able to know for himself that if he uses this forbidden spell he would be committing a crime, and that if anyone finds out about this the direct anger at Azkaban, it doesn't matter if he is a war hero, or if he is the one who saved the world magic of the ravages that Voldemort could cause if he came to power, but that does not matter anymore, because he no longer has anyone important in his life, because his friends died in the war, because the person he loved died at the hands of it person who killed his godfather, leaving Harry completely alone at the mercy of a world that only cared for themselves and that only saw Harry as a magical hero

So what's wrong with an Auror like him using his title to find all kinds of things related to magic, including an ancient dark ritual? Would it be selfish to want to use it for your own benefits? Was the role of idiot and impulsive Gryffindor again? Probably yes, but at this point, what does it matter, if now he is like a shell

The idea itself was to go back to the past, exactly as of September 1, 1994, when he was in his fourth year at Hogwarts, once there talking to Albus and convincing him to be a time traveler, then he would try to gather all the Horcruxes and destroy them, before Voldemort had the opportunity to Rise from the dead and free the Death Eaters locked in Azkaban

So how did your plan fail? What was wrong?

How did it end in 1932?

Or how do I end up in the body of a 5 year old boy?

Or worse yet, how do I end up in the care of a family similar to its horrific uncles the Dursleys?

Couldn't the words Ideas and Potter really go together?

Could it be that the Potter curse really was so bad to not even make a plan like this fail?
