In the justice league no because her skills like I wrote always overlaps with bruce she just uses them for her own profit instead of upholding the law. If she still is a criminal then why is this wedding taking place just for the buzz without making sense. I always thought she be perfect for the suicide squad since harley and ivy and other gotham rogues excluding the joker have been members in the past. She does not work for free except when it involves only people she actually knows or cares about maybe with deathstroke as a fellow merc who does inflitration would be in her wheelhouse.
