The Sound of Drums
The "Doctor Who" episode "The Sound of Drums" revealed that the Torchwood institute itself has been 'redeemed' by Jack, with Jack having rebuilt the organisation in the Doctor's honour after the Battle of Canary Wharf and the Dalek/Cybermen war to be a more benevolent organisation that actively seeks to help humans and aliens in peril rather than regarding all aliens as enemies regardless of their motives for being on Earth.
