Are the sins of the worst people already paid for by Jesus?
Yes. Christ’s death was unique because He is Creator God in human flesh, and on that cross God poured out His wrath for sin. All sin from Adam to the last person was laid on Christ and judged, so even the vilest wicked people’s sins are already atoned for and paid for.
Les explains that the crucifixion was not unique merely as a crucifixion, since thousands were crucified, but it was unique because the One on the cross was the Creator God Himself who took on human flesh. On that cross God poured out all His wrath for sin, and all sin from Adam until the last person who will ever live was laid on Christ and judged. Therefore, even the vilest, lost, wicked people—such as a mafia member—have their sins already atoned for and paid for. Les emphasizes that the only reason such a person would go to eternal doom is rejecting the Gospel, because the sin debt has been finalized once and for all. This is why Paul burned to get the Gospel of salvation out to lost people.
