Wish he wouldn't have killed him honestly. Noah of all people knows what it likes to do anything to get stronger. Shandal waited 60k years just taste the true 7th rank. Noah definitely could've boosted him and broke him out of H&E's cycle. Sad.
Yes Shandal passing was sad, he betrayed his friends and ultimatly the best chance or resisting heaven and earth. he sold out from desperation. however, his abilities and law and memories will assist Noah in ultimate victory.
