Jean later receives former S.H.I.E.L.D. agent Stanley Carter as her partner, and the two develop a close bond, eventually becoming lovers. Unbeknownst to Jean, however, Carter has an obsession with punishing criminals, which is only worsened by his experiences as a cop, to the point where he decides all "sinners" need to die. Suffering a psychotic break, Carter, now calling himself the "Sin-Eater", embarks on a killing spree, resulting in DeWolff being shot dead in her home and Spider-Man embarking on a quest for revenge. Eventually, Spider-Man and Daredevil bring Sin-Eater to justice.
