There's a lot of Jesus imagery with Jack in this fight. His mom's name is Mary, he's grew up without his real father, during the fight he gets pierced in the side, and his whole arc is about forgiveness and unconditional love for all of humanity, even their worst faults. Hercules redeeming Jack is symbolic for Christ dying for the sins of humanity, that's my theory, i might be going too deep into this tho lol
