This is going to be one of Those posts.
When I first discovered Jack 15 years ago, was immediately fascinated by its dark take on the Christian mythology. I was very young at the time - too young to be reading a comic about sexual violence and brutal murder - and while religion was one of my bigger peeves, I found Jack's take on the Hell lore and the seven deadly sins very interesting. The evil deeds of the living may take a physical form in the afterlife, and the seven strongest "demons" in Hell were once the worst human beings (furries?) in life. How fucking cool is that.
To me, his comic reflected the cruelty if the world we live in ("bad stuff happens to good people") and the weaknesses of the humankind ("I was ordered to shoot those children, it's not my fault") while giving him a platform to deal with his inner demons.
Dude has a lot of demons. Make no mistake, Dave is fucked up in the head, acknowledges it and tries to live with it. Since I'm fucked up in the head too, I can sympathize.
Do I think he fapped to someone's childhood trauma? ... No. Not yet, at least, because like CuriousBystander wrote, FC's story is fishy as hell.
He also enjoys gay bashing.
Ehh, it's a little unfair to judge the author for the actions of his characters. Stories need assholes to create conflict. Also, the second page you linked was (IIRC) written by Candy Dewalt and only illustrated by Dave.
I agree that the comic's writing has grown weak over the years, and hit an infuriating low point halfway through Megan's Run. I don't have the pages at hand, but the gist of them is that Megan recalls how the characters of Jack welcomed her into the cast of the comic. I wanted to flip a table.
Edit:
This is
The Wall, a personal "therapy" project by Dave. It is some of the craziest shit you will ever see.
