i agree with everyone who says snape was a gray i think he was not evil but curious about what power he could attain and that i read earliar in the thread about whose to judge good and evil its all perspective its which sideyou are on but i dont feel snape is redeemed for what he did i think he is just even more seklfish than he was before for holding his grudge this long but i am glad snape was the way he was because it changes the series
