I think like Nineveh they lived in darkness and ignorance. God warned Nineveh them beforehand and given that opportunity they repented and God relented.
I think God was just in redeeming those who were under law because in His forbearance He left the sins of the nations unpunished. He was no longer willing to do so hence the wrath of God in the gospel message.
God presented Christ as a sacrifice of atonement, through the shedding of his blood—to be received by faith. He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished—

22But I tell you, it will be more bearable for Tyre and Sidon on the day of judgment than for you
