Actually, innocents have suffered from the sins of others ever since there was sin.
But a "soothsayer" sure wouldn't know that.
Sin has natural consequences yes. Our sin affects others. A mother who takes drugs will pass on the addiction to her baby.
All natural disasters and man made evil IS a result of sin. God created a perfect world and man’s sin ruined it. IOW the sin of Adam and Eve affected us all and the entire planet.
However, Pat is talking about the consequences of sin. He is talking about a direct judgement from God for a certain sin (pact with the devil).
