judges 12

Man talk about a nation divided. Ephraim feeling offended that they weren't called to join the fight answers by gathering their army and confronting the Gileadites. And the Gileadites feel offended that they would dare come and question their actions and insult them, so they in turn respond by killing 42,000 Ephraimites. Talk about short tempers. It is another story of people willing to fight and kill because they feel they are offended. Sounds similar to the story of Pai Mei in Kill Bill. Is it right to take justice (er revenge) in our own hands?
