Qui-Gon Jinn wanted to train Anakin despite opposition from the Jedi Council.
He even convinced Obi-Wan to train Anakin, and although the council eventually agreed with that decision, at the time, it was also against the council's decision.
Other than Qui-Gon Jinn wanting to train Anakin, have any other Jedi defied the Jedi Council to train somebody? Or would have defied the council if circumstances had not prevented them?
The intent of the questions is to ask how often did Jedi defy the council on whom they want to train. If Qui-Gon thought he could defy the council and choose to train Anakin, then perhaps other Jedi had done it and gotten away with it in the past.
