More so than the parallels between Oskar and Jesus or Satan, I liked the Oskar-Judas relationship. His betrayal of his three (that's wierd to think) parents is such a strong part of the novel, that it's no surprise he is compared to yet again, another notorious biblical character. On page 229, Oskar refers to Jan's capture as his own "Judas performance". This is because he sold out his presumptive father, which inevitably led to his death, making Oskar's description an accurate one. Also Grass writes on page 338 that the statue of Jesus says to Oskar, "Dost thou love me, Oskar?" just like Jesus said to Judas. This second parallel again points to Oskar filling the role of not only the messiah and the devil, but the betrayer that turns over his lord to be crucified. Maybe this means Oskar is self-destructive...? I mean he does seem to want to keep himself in a asylum/prison... Also Judas betrays Jesus 3 times (THREE!! TRIANGLES!!) and Oskar betrays 3 parents (ANOTHER THREE!!) so the symbolism is pretty undeniable.
"Judas! Juda-a-a! Judas! Juda-a-a!"
