How do we know God's judgment on Simeon and Levi is justified?

Jacob's revelation of Simeon and Levi as 'instruments of cruelty' speaks to the gravity of their actions in Genesis 34. They deceitfully led an entire city into a false sense of security before executing a violent act of revenge. This was not just a reaction to their sister's defilement; it represented a deeper moral failure involving treachery and violence. Jacob's curse reflects the seriousness of their sin and the consequences of unrighteous anger while simultaneously demonstrating God's sovereign ability to use even sin for His glory. In scattering them among Israel, God ensures that while their actions are met with judgment, they are also positioned to fulfill His redemptive plan.
