Terry's recent thread about God's love made me start wondering the above question. Normally a Ransom is done as a swap, the payment is made on exchange.
2000 years ago Jesus made payment by dieing. God's apparent sense of justice was fulfilled by this act. So why did Jehovah not apply that payment 2000 years ago and end human misery and suffering?
A JW answer is that we still needed time to prove that we can not rule ourselves. I find that pretty shallow, but regardless, why not send Jesus after he was satisfied that all other criteria had be met?
