It could be that he was dealing with deep depression or overwhelming circumstances that pushed him to that brink. But something intervened or he had a change of heart at the last moment.
My answer might not be accurate. In detective novels, the protagonist often found the murderer through reasoning and observation. The plot you mentioned is not a common detective story plot, so I can't provide the name of a novel. If you can provide more information such as your favorite author, an outline of the story, etc., I will try my best to provide you with a more accurate answer.
There might be some extremely dark and non - canon fanfictions out there with such a disturbing plot. However, this goes against the general spirit of the Harry Potter series. In the official story, Harry is a hero who overcomes great challenges. In a fanfiction with this idea, perhaps it could be due to extreme despair from losing too many loved ones or feeling an overwhelming burden of his destiny that he snaps and takes his own life. But again, this is a very unorthodox and sad take on the character.
For example, in an anime where the protagonist's friend is killed by the enemy and then goes berserk, you can refer to the following example:
" The Blade of Ghost Destruction ": The story tells the story of a villain organization called Onimaki Tsuji Asamatsu, who turned the entire Japan into ruins in order to achieve his goal. The protagonist, Ashijiro, is a young man who fights against Onimaki Tsuji Asamatsu in order to save his family.
In the battle between Azhiro and his friends, Chihiro and Orochimaru, they were attacked by the enemy. Chihiro was unfortunately killed by the enemy in order to protect Azhiro.
When Tanjiro learned of Qian Xun's death, he began to lose his mind and fell into extreme grief. After Chihiro's death, Akashiro's body began to become abnormally powerful and he was given the title of "King of Ghost Hunters". He began his journey to save the world.
In the process, Tanjiro continued to fight against various enemies and continued to grow in the state of rampage. In the end, he successfully destroyed the ghost dance and saved the whole world.
😋I'm very happy to recommend "I'll become stronger in my dreams" and "I'll become stronger in my dreams when I'm in high martial arts!" These two novels both meet your requirements. The protagonist will become stronger after killing monsters in his dream. They belong to the fantasy-high martial arts and urban-urban life novels respectively. I hope you like this fairy's recommendation. Muah ~😗

Well, my friend was camping near a river. He decided to go for a swim. Unbeknownst to him, there was a strong undercurrent. As he swam further out, he got caught in it. He struggled hard to swim back but was being pulled downstream. Just when he thought he was going to drown, he managed to grab onto a fallen branch that was sticking out from the riverbank. With all his might, he pulled himself to safety. It was really a close call.
Well, for the Harry Potter fan community, it's a bit of a shocker. The community is used to the idea of Harry as a survivor and a fighter. Such a fanfiction can create a divide. Some might be intrigued by this very different take on the character, seeing it as an exploration of the extreme. But many would be put off because it doesn't align with the spirit of the books. It could also make some fans question the boundaries of fanfiction and what is acceptable within the community.
There were many such novels, such as " Battle Through the Heavens " and " The Peak of Martial Arts ". In these novels, the male protagonist usually had a friend or classmate who became stronger after they transformed. This kind of plot often attracted the interest of the readers and made them pay more attention to the growth and changes of the characters.
