It does not matter what I believe. The past is done. Hope is irrelevant. We measure success and failure in history with a cost of lives. Penicillin saved people, and the world wars exterminated them. Success and failure. Feelings, regrets, the point where they knew they made mistakes...it is interesting but unfortunately, irrelevant. Did they go to their death and grieve for what they did? Did the makers of the atomic bomb grieve for the destruction they dedicated their lives towards creating? Who cares? They did it. Whether they knew what they were creating, or whether they talked themselves into believing it was for the best, the glory of history is being able to view it in black-and-white. However honorable one's initial intention, a villain will always be a villain.
