Under the stipulations of Section 2127 from the established Imperial Penal Code, Imperial Assassins were obligated to inform their intended victim that they had been contracted for a sanctioned assassination. The reason for this notification was to allow the target to atone for transgressions against Humanity that they had perpetrated. Subsequently, the code mandated that the assassin furnish the victim with a weapon, acknowledging their lawful entitlement to self-defense. Furthermore, a three-minute waiting period was imposed before the assassin could proceed with the assassination attempt, ensuring the victim had a chance to flee.
Dengar, whose alias was "Payback", adhered to these regulations.
