Jesus uses this question to challenge the understanding of the people. He answers the question in 13:4. Alternate translation: "does this prove that they were more sinful ... Jerusalem?" (See: [[rc://en/ta/man/jit/figs-rquestion]])
The crowd assumed that they died in this terrible way because they were especially sinful. This could be explicitly stated. Alternate translation: "they died because they were worse sinners" (See: [[rc://en/ta/man/jit/figs-explicit]])
