Overview
Jack covers subjects related to the attitude persons can exhibit in life, as well as its consequences to them and to the people around them. Frequent features are disease, rape, murder, suicide, bereavement and redemption. The comic is divided into a number of arcs (subplots) of varying length. Artwork style and presence of color differ from arc to arc. Arcs take place on Hell, Earth, Heaven and Purgatory. Arcs set on Earth take place during different, not always consecutive, time periods. In Heaven and Hell there is no concept of time. The eyes of characters symbolize their status in the Jack universe: sins have no pupils; living souls and angels have full pupils; the souls of deceased persons have "pin-prick" eyes as long as they do not recognize their sins.
Jack is based on Christian tradition, but the world and its rules are inconsistent with typical Christian views. The angels are the forces of good, and the sins are evil personified. Many of Hell's denizens enjoy inflicting pain on one another. However, there is confusion at times, with people who were good in life end up going to Hell. The unfairness of the fates of many of these people, and the observations of Jack on the unfairness of life, are central themes to the comic.
