No, Jesus was killed to pay for our sins. Sin demands punishment; God has always said so. But the Good News is that God Himself — Jesus Christ — willingly took that punishment onto Himself. No one could have killed Him had He not allowed it, as He Himself said (John 10:18).
Sacajawea’s comment was about the reasoning of the killers, not about God’s purposes. The people’s motivation in killing Jesus wasn’t to facilitate Him paying for our sins, they wanted Him dead to shut Him up because they viewed Him as a popular figure and a heretic who was a threat to their power and status quo.
Didn't work - but that was their motivation.
> No, Jesus was killed to pay for our sins.
BOTH are true.
Those who killed Him were not Christians, they did not believe in Him, they didn't know about much less accept and believe, that His death would pay for our sins. We know that; the Establishment of the time did not.
On the contrary, the Establishment killed Him for what He said (His teachings), and the existential threat He posed to the Establishment of the time.
Jesus last statement on the cross was to the Father God:
Unto Thee I commend my Spirit.
No one killed Him, He gave up His life for our sins.
For the sins of the world.
