agree on some level with most of what's posted above, so this next point isn't an argument against any of it.....
supposedly anakin's rebellious nature and anti-authoritarian stance was passed from dooku to qui gon, and then on to anakin....this has been stated oficially a long time ago (though don't ask me where, or for direct quotes)..... if qui gon had survived to train anakin then, i guess you might think this would have exaggerated the problem rather than avoided it....
but on a gut level i think it would have been better for the reasons everyone else has stated....
oh yeah, another thought....keeping in mind that qui gon and dooku supposedly had so much in common, and how strongly qui gon felt about anakin's training, even against the wishes of the council, is it possible qui gon might have quit the order to train anakin outside the jedi establishment?.....just a thought.....
