Albert Barnes Commentary Proverbs 1:29-31

"For that they hated knowledge, And did not choose the fear of Jehovah: They would none of my counsel; They despised all my reproof. Therefore shall they eat of the fruit of their own way, And be filled with their own devices." — Proverbs 1:29-31 (ASV)

This is no arbitrary sentence. The fault was all along their own. The fruit of their own ways is death.
