So Harry would have to deal with the prejudices of his Gryffindor - loving friends.

Maybe he would start to understand the Slytherin values in a different way, like ambition not always being a bad thing.

If Harry Potter was assigned to Slytherin, it would be a very interesting and very different setting from the original. Judging from the characteristics of the school, Slytherin students were often ambitious, shrewd, cunning, and had strong leadership skills. Harry Potter had strong leadership skills, and if he had been in Slytherin, this ability might have developed in a different form in the Slytherin environment. His ambition might no longer be just to defeat Voldemort, a simple goal based on justice and survival. It might include gaining recognition within Slytherin and improving his status. Judging from the interpersonal relationships of the House, Harry might have had a different relationship with a Slytherin character like Severus Snape. Snape had been secretly protecting Harry because of his deep love for Harry's mother, Lily. But if Harry was a Slytherin, Snape might guide and protect Harry openly. After all, Harry showed the same magical talent as his mother. Within Slytherin, Harry might face the challenge of pureblood. Slytherin House had the pure-blood values inherited from Salazar Slytherin, and Harry was half-blood. This might cause him to be discriminated against by some pure-blood wizards, but Harry might also be able to change the way some Slytherins viewed half-bloods, just as he had done in the original novel. If Harry had been in Slytherin, his understanding of Voldemort would have been deeper and more direct. Voldemort was the heir to Slytherin, and Slytherin House was closely related to the Dark Arts. Harry might be able to get more information about Voldemort and the Dark Arts from within the House, which would give him more information resources on the road to fighting Voldemort, but at the same time, he might face more temptations or direct dangers from Voldemort and his followers, the Death Eaters. Under this setting, the relationship between Hogwarts colleges would also undergo a huge change. The traditional opposition between Gryffindor and Slytherin might be complicated by Harry's presence. He might become a bridge between the two Houses, promoting cooperation and understanding between students of different Houses. Harry Potter and the Sorcerer's Stone was not enough.
