The vast majority of disciples were thrilled to hear the announcement that the Nethermoon Sect was about to retaliate against the forces who launched the sneak attack on that tragic night. Lee was not one of them.
Not only he had no deep attachment to the sect and didn't intend to lay down his head for it, he was not a big fan of large warfare in the first place. It was no secret that during a war mostly the little people died, and currently he was one of them.
