Such actions without repentance are meaningless. What brings the greatest joy in heaven is the repentance of sinners. As I noted earlier, the present tense of the verbs in our text indicate living repentantly, rather than seeing repentance as an occasionally act. I don't think that Jesus implies that if someone is not repentant, that they will die an untimely death as the people in the illustrations. There is some truth to this cause and effect notion.
Chain smokers are more likely to suffer from lung diseases.
Drunks who drive drunk are more likely to suffer an accident. Our medical science assumes that there are definite causes for illnesses. In our text, Jesus does not deny that those who were killed by Pilate or the tower were innocent victims. At the same time, the pain and suffering caused by human sinfulness are not all equal. They need to repent.
