Luke 13:2

“Or those eighteen who died when the tower in Siloam fell on them—do you think they were more guilty than all the others living in Jerusalem?”

Appears in the immediate context with a similar theme of not being worse sinners than others.

“His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” “Neither this man nor his parents sinned,” said Jesus, “but this happened so that the works of God might be displayed in him.”

Addresses the common misconception that suffering is a direct result of personal sin.

“Then Jesus began to denounce the towns in which most of his miracles had been performed, because they did not repent. “Woe to you, Chorazin! Woe to you, Bethsaida! For if the miracles that were performed in you had been performed in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. But I tell you, it will be more bearable for Tyre and Sidon on the day of judgment than for you. And you, Capernaum, will you be exalted to the heavens? No, you will go down to Hades. For if the miracles that were performed in you had been performed in Sodom, it would have remained to this day. But I tell you that it will be more bearable for Sodom on the day of judgment than for you.””

Concerns the judgment to come for those who don't repent, which is what Jesus is warning about in Luke 13.

“What shall we conclude then? Do we have any advantage? Not at all! For we have already made the charge that Jews and Gentiles alike are all under the power of sin.”

Teaches that all are sinners and no one is inherently better than anyone else.
