Jax didn't get either of those. He unceremoniously became a non-character off screen. It's not tragic, horrific, or cathartic. This is not playing by the rules of killing a character. My horrible epiphany came when I ignored the rules of an actual story and paid attention to the pet play subtext and other fetishes discussed in this thread. A lot of fetishes in niche porn like TF are inflicted on ordinary people who sometimes "deserve" it, and because they're not important or powerful and the artist doesn't want a serious tragedy, they'll justify it just by making them jerks as if that's enough to justify their rape or ego death. He wasn't abstracted as punishment for being a jerk, he was a jerk as retroactive justification for having him abtracted.
TL;DR: Jax was abstracted for the fetish.
