The Spectacular Spider-Man #134 (1988)
“Sin-Eater Released, Part 1: Sin-cere”
Writer: Peter David
Artist: Sal Buscema
Sin-Eater (aka Stan Carter) is released from the mental hospital where he was sent place of jail. Spider-Man hears of this and goes to pay him a visit to scare him to make sure he doesn’t kill anymore people. He finds just a frail, broken man with a stutter and discovers that he was the one who gave him a limp and a bad ear and a stutter. Shaken from this, Spider-Man is beaten by Electro, who finds a way (via static electricity) to eliminate Spidey’s ability to cling to walls.
