Growing up Pureblooded

What would happen if Harry Potter was saved from the Dursley's and instead raised as the pureblooded son of Sirius Black. Will he end up following in the path that seems to be common for most purebloods, or will he change the status quo and still be the hero that the wizarding world needs?

Inspiration for this story comes from a fanfiction on fanfic.net that is unfinished and I created an ending for it. Harry Potter and the original world belongs to JK Rowling what is mine is the continuation of the original story and added details.
