The trauma from that fateful night... it changed something inside of Jackson... something irreversible...broke. If his brothers were gone, and if he was all alone in a world that hates villains like him... then what even was his purpose in the first place? Jackson swore that he wouldn't let the girls get away with this... even if he couldn't defeat them head-on... he would make them pay for what they did... And unlike what the girls dealt with HIM... they wouldn't be able to use the power of Sisterhood to repair the damage done to this poor child.
