His banishment to Earth was short lived, though he didn't immediately return to Pride. He turned his attention to his Fighting Pits in Wrath. Though he made himself comfortable at his club, Satan summoned him to his palace where Jack was hosted for a while. The prince entered a bit of a mentorship with the Sin, and plenty seemed to 'click' in place. Satan had plenty of knowledge about Jack's role as the Antichrist and helped him tap more into his chaotic power.
Eventually, his return to Pride happened, but it was strictly for the sake of duty. Satan wasn't pleased with the shake-up of the status quo and wanted it back to how it was.
It wouldn't be senseless, though Jack was itching for some mayhem, Satan reminded him of his rank and duty.
Sinners and Hellborn were brought forth if caught stepping too far out of line for the Sin's liking. No need for a grand trial with all other Sins or royals present. Just a few witnessing Satan mentor the Antichrist. Hell had laws, even if at times it felt like a lawless land. Jack enjoyed the privileges of being a prince, but he also had to prove he was willing to do what it took to be a pillar of Hell.
"You were brought forth the infernal court for your crimes against Hell. You've been found guilty. Your sentence is...death." Jack declared as he stood from his throne.
There was no executioner...because Jack was the executioner. He extended his claws as he cupped the Sinner's face. Jack's eyes glowed though his expression remained regal and cold. His claws dug into the Sinner's face, previously they've been dipped in a venom of Jack's own making. The venom would spread in form of black veins, the Sinner's blood feeling as if it was turning into acid and burning them from the inside while disintegrating their bones and organs. Jack continued to hold their face and look into their eyes. Being the last thing the Sinner saw before perishing. The screams were limited since the venom was fast acting and would affect the vocal chords soon.
Jack watched the lifeless body for a moment before making his way back to his seat. To Yogirt, he said evenly, "We have a full docket, so let's not delay. Remove the waste and bring in the next offender."
