@Griffith Augustinian type response, but less good because I'm not as smart.
What is good? Jesus Christ said "No one is good except God". We have a choice in behaving in the ways which please God, or the ways which don't. The nature of the world around us makes it functionally impossible to be "good" on our own merits alone, as a result of mistakes of our ancestors. That we were offered a second chance rather than bound by the same curses which afflict them is love. A lack of love would be to tell us "we cannot be redeemed" (Satan soyjak screaming DO NOT REDEEM SOUL!) and the only one who says that is Satan and his demons.
