But should we consider any Japanese person innocent? They were supporting their government weren't they? Their government was the enemy of the United States, and they (the government) had attacked us. We could not allow that! Vengeance for the dead at Pearl Harbor demanded that we only accept an unconditional surrender from the people who had taken their lives. America deserved its revenge!
In all reality, it is this mindset that has lead to the Iraq and Afghanistan Wars. I recently heard one of the Presidential candidates criticized because he didn't mention revenge as a response when asked how he would respond to another terrorist attack. Are we really that advanced a society? We're still promoting revenge... are we still in junior high? is the President supposed to act like the Godfather?
What Jesus' life teaches us is that the world is not made better through revenge. Think about it, he is raised from the dead, what's stopping him from going back to the temple and having a little face to face with the priests? What are they going to do try to kill him? He's spending time with his disciples, explaining to them the point and purpose of his death. If there is anybody who has a right to revenge it's Jesus, but he refuses to play that game.
The cycle of revenge does not lead to resolution. World War II was a result of World War I (I know, very ironic.) Revenge only leads to more revenge. Until your family is feuding with another family for 150 years (think: Hatfields and McCoys). Revenge leads to bitterness and anger issues. Revenge leads to death. Revenge leads to killing thousands of people instantly with an atomic bomb.
