Luke 13:2

‘And he answered and said to them, “Do you think that these Galileans were sinners above all the Galileans, because they have suffered these things?” '

This confirms that there had been some suggestion that they had brought their suffering on their own heads, or possibly even the suggestion that for someone to be killed while actually in the process of bringing a sacrifice must prove what dreadful sinners they were. The idea has become fixed in some people's minds that these were particularly sinful Galileans. Note Jesus' description of them as having ‘suffered'. It connects back with the suffering He is bringing on the world (Luke 12:49). They are examples of the fire that is coming on the earth.
