In a similar Q to BaalHabooze:
Q. How was Rochel allowed to give the “secret password” to Leah? She was a traitor!
Imagine the story today. Some young BJJ graduate comes home from Israel, and gets engaged to a Lakewood bochur fresh out of the freezer. Ms. BJJ graduate has an older sister, with very sad eyes, at the grand age 27. After three months of palnning every last detail, the day finally arrives. At the chasunah the chosson goes and “badekt”s the kallah. They have a very moving and uplifting chuppah, and immediately after the chosson breaks the glass, the kallah lifts her veil and behold there stands the kallahs sister!!
Would the kallah be considered great for saving her older sister or would she be a traitor to her new husband??
And what needs further explantaion, how could it be that this very action gave Rochel her prestigious place in Klal Yisroel?!
