okay people if revan went to find the true sith and the true sith can detect force users then revan would have had to learn to hide this fact for the 4 years he was in the outer rim. as in kotor 1 they explained if a jedi master had accompanied them it would present them as a bigger target. but revan would know this as he would be the biggest target of all as kreia said he is the heart of the force. so he would have had to abandon his force training and with time he lost his combat abilites and his use of the force. to protect himself for the greater good of the republic and kreia always emphasised that when revan was captured by bastila and the jedi council, that it was not much of a task to show to revan that in his heart was always a lightsider. and it was arrogant of the jedi council too think they turned him to the light as he never left he simply shifted to do wot was best for the war against the true sith.
