YMMV / Justice League S 1 E 6 And 7 The Enemy Below

• Complete Monster: Lord Orm is the treacherous and power-hungry half-brother of Aquaman. Resenting his brother for having never wiped out the surface-dwellers, whom Orm despises, Orm seeks to usurp the throne from his brother and wage a war against the surface-dwellers to eradicate them. To achieve this end, Orm hires Deadshot to assassinate Aquaman, blaming the attack on the surface-dwellers and using this as a means to justify war, forcing Aquaman's wife Mera to cooperate by threatening her infant son. When Aquaman returns, Orm reveals his treachery by abducting him and chaining him to a cliff near a volcano. To ensure his place as ruler over Atlantis, Orm attempts to plunge both Aquaman and his son into the volcano, forcing Aquaman to severe his own hand to save his son. Orm then arms an Atlantean thermal reactor to melt the polar ice caps, thus submerging the entire planet underwater and sentencing all surface-dwellers to death.
• Moral Event Horizon: Orm crosses it when he hires Deadshot to assassinate Aquaman, and then doubles down by attempting to dip him and his infant son into a volcano.
