After the success of Gideon's victory over the Midianites by the grace and working of God, Gideon's life ends in turmoil. Rather than humility, God's grace in Gideon's life leads him to pride, to assume the role of the king and exact revenge on those who defy him.
Following Gideon's death, Gideon's son Abimelech then sends Israel into further turmoil until God judges him for his sinful and underhanded ways.
