i'm not sure i should post this here but i'm looking for an ultimate spider man fic. i read this a while ago so not all the details are there. peter quits sheild fury tries to use his Aunt to get him not to but he still does so she disowns him, and he ends up getting adopted by Norman Osborn. from what i rember Norman, harry and peter end up doing evil things together.
PS peter uses carnage after being adopted by Norman
