You or I are no more directly responsible than the Roman soldiers that put the nails through his body. God created this world, including the unavoidable way of sin and he planned that his Son would be sacrificed from the beginning as well.
God himself records that the Jews were responsible but God also decided that is who would be same that Judas would be the betrayer. God has decided all these things.
Oh I'm directly responsible all right. If I was sinless I could say it wasn't my fault, but unfortunately I cannot say that.
John 10:14 "I am the good shepherd, and I know My own and My own know Me, 15 even as the Father knows Me and I know the Father ; and
I lay down My life for the sheep. 16 "I have other sheep, which are not of this fold ; I must bring them also, and they will hear My voice ; and they will become one flock with one shepherd. 17 "For this reason the Father loves Me, because I lay down My life so that I may take it again. 18 "No one has taken it away from Me, but
I lay it down on My own initiative. I have authority to lay it down, and I have authority to take it up again. This commandment I received from My Father."
