The lesson of Galactica and treating your creations well
A few weeks ago I reviewed the disappointing "The Plan" and in particular commented on how I wished the Cylons really had had a plan of some complexity.
More recently, I was thinking about what many would interpret as the message in BSG, which is said by many characters, and which is at the core of the repeating cycle of destruction. When you get good enough to create life (ie. Cylons) you must love them and keep them close, and not enslave them or they will come back to destroy you. This slavery and destruction is the "all this" that has happened before and will happen again.
Now that it is spelled out how the whole Cylon holocaust was the result of the petulance of Cylon #1, John, and that this (and its coverup) were at the heart of the Cylon civil war, the message becomes more muddled.
For you see, Ellen and the other 4 did keep their creation close. They loved John, and raised him like a boy. Ellen was willing to forgive John in spite of all he had done. And what was the result? He struck back and killed and reprogrammed them, and then the rest of his siblings, to start a war that would destroy all humanity, to teach them a lesson and in revenge for the slavery of the Centurions. Yet John was never enslaved, though he did decide he was treated poorly by being born into a human body. It's never quite clear what memories from the Centurions made it into the 8 Cylons, if any. It seems more and more likely that it was not very much, though we have yet to see the final answer on that. Further they enslaved the Centurions and the Raiders too.
So Ellen kept her creations close, and loved them, and the result was total destruction. Oddly, the Centurions had been willing to give up their war with humanity in order to get flesh bodies for their race. The Centurions were fighting for their freedom it seems, not apparently to destroy humanity though perhaps they would have gotten to that level had they taken the upper hand in the war. Ellen intervened and added the love and the result was destruction.
I don't know if this is the intentional message -- that even if you do follow the advice given to keep your creations close and loved, it still all fails in the end. If so, it's an even bleaker message than most imagine.
