"Revan also saw a situation where a Jedi master decided to push their pupil to fall to the Dark Side. On purpose. In order to help them grow. Which can almost sound okay, if you spin it right, if you make it about showing the student both sides of the coin. Except it involved traumatizing at least one student into hating themselves and falling to the Dark Side because they thought that was all they could do. That they were damned, forever. They were left like that for a while, and while they were there, they caused nearby animals to become more dangerous to the nearby settlers.
"Then, what Revan considered to be worse, Revan was asked to deal with them. With no specification as to how, or detail of the history associated. Revan was - well, Revan was Revan, so they didn't interpret that as 'kill them to protect the settlers' and instead interpreted it as 'help someone when they're in a very bad place,' and ultimately redeemed and befriended them. But if anything in that sequence of events had gone even a little bit wrong - if the fallen student had decided to leave the planet, if the fallen student had thought that being irredeemable meant that the only way to save themselves was to take their own life, if someone had been seriously hurt by the wildlife they'd stirred up, if Revan had just accepted what the Jedi Council had handed them at face value..." The holocron trails off, then shakes his head. "I think you should watch for Jedi arrogance, and Jedi making decisions about risk that aren't really theirs to make. Because it was never any of them that were in danger, it was the student, it was the settlers, it was the wildlife. And they deemed risking all of them acceptable."
