Saddam's Execution a Crime?

According to Cardinal Renato Raffaele Martino, the head of the Vatican's Justice and Peace department, executing former Iraqi leader Saddam Hussein would be "avenging a crime with another crime".

This is ludicrous. It's called justice not crime. Mass murder is a crime. Saddam, unfortunately, lived to go through a justice system that could have proved him innocent. He is going to be put to death in a quick and humane method. Something his hundreds of thousands of victims never enjoyed.

The execution of saddam is justice. He will never murder again.
