The Good Slytherin

"Not all Slytherins are inherently bad, and I'm going to prove it!" Such is the declaration that Harry Potter makes after the famed Chosen One is sorted into Slytherin. He sets out to find the good in his housemates, not realizing that his quest brings out the bad in him, or that his own sorting has brought him into closer proximity to the very wizard who wants him dead the most.
