[spoilers] Sir Harry Pearce 2.0

[Silktie]

I do too. I think to Harry, to have sacrificed Ruth would probably have been the final step that truly killed his soul. In the end he chose to be human for once, and chose his own humanity over the greater good. In the long run, he wouldn't have been able to live with it if he'd sacrificed Ruth, and he would have been no good in his position anyway, methinks. Harry needs his soul to be alive to be able to make the best possible decisions. On some level he knows that.
