Why not just be a decent person without being threatened? It's how the majority of people in the world do things.
"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast." - Ephesians 2:9
"know that a person is not justified by the works of the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by the works of the law, because by the works of the law no one will be justified." - Galatians 2:16
So Christianity is simply placing your faith in Jesus Christ. If you believe that God forgave your sins at the behest of Christ, and that you will enter an eternal kingdom also as a son of God, wouldn't you eventually be more liable to forgive and love others?
So being good is a side-effect, not the point, of Christianity. God will not let me enter heaven because of how good I am, and if that was the measure none of us would make it. The point of Christianity is to know God and have faith that through Christ's death on the cross, burial, and resurrection, he can impart the mercy of God onto you. That he quite literally died for every sin everyone had ever committed.
“For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.” - 2 Corinthians 5:21
It reminds me of highschool, where, while waiting for a teacher to arrive, another student declared to me that they "knew the chemical formula for a human" and then just listed six or seven elements without any regard for (1) that's not what a chemical formula is, nor (2) a human isn't a single chemical, nor (3) all the other elements in a human body.
What you're listing (clearly inspired by the ten commandments) wasn't sufficient for Judaism, Christianity, or Islam, even though at least two of those rose to dominance within preexisting civilisations that had a whole bunch of extra rules.
Those other rules included things like "pork goes off really fast in a desert so just don't even risk it" and "when we said don't kill other people we weren't talking about those specific foreign soldiers currently waving their spears around" and "crop rotation is good".
More recent things that the linked story is talking about includes "how to help women give birth without dying".
Maybe he was just joking around?
