Commentators highlight a crucial principle: God judges the motivation behind our actions. Jehu was commanded by God to destroy Ahab's dynasty, yet his house is judged for shedding that very blood. Scholars explain this is because Jehu acted out of personal ambition, not pure obedience. He selectively obeyed God, destroying Baal worship but continuing the idolatry that secured his political power. This shows that even doing a 'right' thing for the wrong reason is a sin in God's eyes.
