According to TBS's definition of morality from the video, torturing the extremists would cause unnecessary harm and suffering, and would therefore be immoral. We live in a reality where torturing people isn't the only means of saving people. Asking whether or not morality is determined pre or post facto is an interesting question that I don't know the answer to. Do you have a definition of morality that answers this?
Anyways, the point of the video was not to say that his definition of morality was the right one or perfect, but that a concrete, non-circular definition used to promote general well-being is infinitely more useful than a circular definition based on the "nature of God".
Wait bud. By definition if torturing a few extremists with purpose to save a billion people, according to your statement on morality it is justified and righteous. Isn't it?
I would disagree with the video's premise that Christian's explanation of morality is simply saying the "nature of God". It is much more complex than that.
Asserting that God is omniscient and absolute truth is asserting that there is the opposite. Sin, false truths, lies.. etc. Asserting that God is righteous puts an identity on what those things are. What is righteous? Well we look at God's character. He is justice, mercy, gracious, loving.. all these things are what we consider moral.
Then we look at the opposite which is immoral and sin. These things are brokenness, death, murder, war, etc etc. These things are depicted in Scripture.The video claims that Christianity's view on morality is flawed circular logic because the video itself does not see Christianity's measurement of morality itself
Scripture is what defines morality for us. It is the Word of God. The video makes this claim of "then God is just the messenger of this morality".... well isn't that interesting? God, as Christians see him as, he IS the Word.
God is the law, the deliverer of the law and also the nature of law itself. If that is circular logic, then I am sorry, God cannot be fathomed by mere human minds. If you could put him into words, then that already defies the nature of a higher being.
