The doylist explanation is that a lot of religions back in the day practiced animal sacrifice to their deities (including judaism, e.g. Noah sacrificing animals after the flood and Abraham sacrificing a ram in place of his son once god was bored of telling Abraham to kill his kid to prove his faith). Jesus getting sacrificed is supposed to be a mirror of this for Christians and an “ultimate” sacrifice. They don’t sacrifice animals to god anymore because jesus just keeps doing the heavy lifting for them.
That’s not an actual answer though, it’s just a politician’s “answer” and then pretending afterwards that the question was answered. Free will means you can change your mind. If you can change your mind, it’s possible that you would change your mind at the very last second. However, if it’s possible to know ahead of time with 100% certainty what someone will do, then they don’t actually have the ability to change their mind at the last second, and any concept of choice is an illusion.
The second quote only addresses why god isn’t at fault if free will exists, and therefore doesn’t address the issue
