Jackals are scavengers, carrion eaters, and are thus metaphorically cloaked in the stench of death. This gives rise to the obvious association with death, but in making the jackal a god, the negative connotations are re-framed into a more positive perception. Anubis becomes the god of embalming, and thus is seen as caring for the immortal soul of the deceased. This loving preparation of the dead is the feel good sacred bit, even as the enevitabliity of death is the primal sacred truth that gets covered over. At a more religious level, the jackal is loving because it cares for the soul, and is a type of psychopomp. At a more atavistic level, it returns the energy of the deceased to the cycle of life, mirroring the religious meaning in a way, but also embodies both the fear of death, and the longing for the surcease of pain. My take. Remember the salt.
