Will you do it?

"The choice given only applies to those who are innocent, and the choice is simple they can leave the sect temporarily until the sentencing has passed or they can choose to face it with the rest. 

Ultimately it is up to them. If they choose to remain, then regardless of their innocence in the matter, they will share the same fate as the guilty.

Wei Ying's and Mo Liwei's verdict was to help you come to terms with this eventual reality. You may give them the option to leave, some may take it, others may not,  they may all take it or they may all decide to stay.

You therefore need to prepare yourself that you may indeed be forced to destroy the entire sect in the execution of the sentence.

As the judge in charge of this case, the burden falls on you first then to the rest. You cannot be half-hearted about it in the least.
