Imagine you had a time machine. You could go back in time and change anything you wanted. A past mistake could be erased, a missed opportunity taken, a relationship saved. If I had such a time machine I would change nothing. I would leave everything exactly as it happened, including all the regrets.
A popular attitude suggests many people would go back in time and kill Adolf Hitler before he committed his crimes against humanity. I wouldn’t. I would let the approximately 60 million people died; I would allow the gas chambers to continue.
Why would I pass a chance to save all those people? Am I really that cold? No, I am not that cold, but I do know everything happens for a reason. If Hitler didn’t do what he did more than a billion people could have died and the human race sent back to the Stone Age.
Imagine a time machine existed allowing anyone to go back and kill Hitler before the nightmare began. Imagine someone bumped off little Adolf when he was a wee tyke. How would human history have evolved differently.
