Re: One particular SPOILER from The Name of the Doctor
I'm going with Time War incarnation who stopped calling himself the Doctor. Presumably throughout the war he did things he's so ashamed of, things he considers worse than comitting genocide against the Time Lords and the Daleks. I could see this fitting with Smith describing him as the one that broke the promise, as well as Hurt's line about being choicelss and doing what was necessary in the name of peace and sanity.
