Finding a very specific 'Harry Potter' fanfic can be a challenge. You could also join 'Harry Potter' fanfic groups on social media platforms like Facebook or Reddit. Explain what you're looking for in your post. Fans are usually very helpful in these groups and might be able to recommend a great fanfic that involves an assassin being betrayed by Moody. Another option is to look through the works of popular 'Harry Potter' fanfic authors, as they might have written something similar.
I'm not sure of a specific one off the top of my head. But you could try searching on fanfic websites like FanFiction.net or Archive of Our Own. Use the keywords 'Harry Potter', 'assassin', 'betrayed' and 'Moody' in the search bar to narrow down the results.
There are so many 'Harry Potter' fanfics out there. It might be a bit difficult to find one that exactly matches this description. However, some fanfic communities have recommendation threads. You could post in those asking for a fanfic with this plot. Maybe someone has read it and can point you in the right direction. Also, check the tags on fanfic sites carefully as sometimes the plot details are hidden in the tags.
Perhaps the assassin is a double agent, and Moody's betrayal is part of a much larger scheme. The assassin could be pretending to be betrayed to gain the trust of the real villains. So, the assassin then uses this new - found trust to gather information and save the day in the end. Another plot twist could be that Moody is not the real Moody, but an impostor who betrays the assassin for reasons related to the impostor's true identity and motives.
Maybe it's a character who has a hidden identity. It could be someone who was thought to be dead but actually survived and is now seeking revenge. This person could have a grudge against Moody for something that happened in the past. Or it could be a new character created specifically for the fanfic, a dark wizard from a far - off land who has been hired to kill Moody.
Well, one possible motive could be that the assassin is working for Voldemort. Moody was a powerful Auror and a threat to Voldemort's plans. By eliminating him, it would clear the way for the Dark Lord's operations. Another motive might be personal revenge. Maybe Moody had put someone close to the assassin in Azkaban in the past, and this was a way to get back at him.
A great 'betrayed Harry Potter fanfic' is 'Alone and Betrayed'. This story takes a different turn where Harry is not only betrayed by friends but also by some of the Hogwarts faculty. He has to rely on his own wits and some unexpected allies to fight against the forces that are trying to bring him down.
Well, I haven't read a particular 'godlike Harry Potter betrayed' fanfiction myself. However, the concept sounds really interesting. It might involve a Harry Potter who has some sort of god - like powers and then is betrayed by someone he trusts.

It could be that the assassin was initially a victim of some dark wizard's experiment. Harry, being the hero he is, feels responsible for the child and decides to raise him. In the process of raising, he unknowingly nurtures the assassin-like qualities in the child because of the unique circumstances and challenges they face together.
One way to find 'Fem Harry betrayed' fanfics could be to join some Harry Potter fanfic communities or forums. There, you can ask fellow fans if they know of any such stories.
