Not even remotely. You are hung up on this idea that asking God "why" is a sin, the passages you've provided to back such a notion up do not support this idea of yours. The Father never abandoned His Son, and the Son never fell short of His Father. Even in death the Son of God was in perfect union with His Father. The Church proclaims that Hades took a man and encountered God, it took earth and encountered Heaven--and when it did so it was despoiled. The death of Christ is not defeat, but victory; for death is swallowed up in victory. He is risen.
"Christ is risen from the dead,
Trampling down death by death,
And to those in the tombs,
Bestowing life."
