"Am I a good man?"
That question is going to haunt me for the rest of my regenerations.
The first time I asked Clara Oswald that question, she did not know how to answer it, but from her look, I could see she was full of honesty.
Asking her that question again today, her answer was immediate and equally as honest now as it was soul destroying.
"A good man would never do that to his worst enemy," she said as stood by the TARDIS door.
Without even looking back at me and leaving the door for the last time, she added "And if you have any shred of decency left in your body, you will never, ever contact me again."
Having stared at the door where she had stood for what seemed like a lifetime, I played over two moments in my mind time and time again. In changing the course of history, my history, in changing the time war and hiding my home world of Galifrey, I made the biggest miscalculation of my entire life.
The moment Galifrey was taken out of our universe, an army of Daleks was left behind with no one to fight. And there was nothing worse than that army whose sole hatred of the time lords was to become focused on only one. Myself.
It took them time to track me down, but with no time-lords to monitor and control time travel, they had the freedom to hunt me down, leaving me no choice but to change the course of history again.
The repercussions will spread across the universe and an action I will stand by for the rest of my life, but Clara did not agree. She saw the death and destruction that was to follow, as well as my own sacrifices.
I let the Daleks live once before, I could not leave that mistake unchanged for ever. Whatever the personal cost to me.
These are the events playing over and over in my head, as they all start again right now from the moment I learned the truth of my actions as Galifrey Falls No More.
