You see? You are using the same hypothetical reasoning.
You may say that even if you killed the guy, you at least did not do that intentionally.
Then I would say, can you prove me that was the intent of Chaim. And the answer is no. He did his time for political protesting.
By the way, if you lived in Russia, you would have gone to jail for killing or even injuring someone on the road. There was no insurance there.
Now, what is the chance of a mass murder occurence when you crash a plane into a skyscraper?
99.99%. Right?
Osama is a bad guy. You and Chaim are good guys.
