Honestly this is probably the best way this could have ended; I mean he complained before the start of the battle that he wouldn't be fighting a grand champion of mankind, but if he did, would he really have fought like he did right now? Fighting someone like Lu Bu or Adam would have just been strength vs strength, which would have made Herc win outright, but he would have hated it since that would mean being the nail that would lead to killing mankind. This fight, however, where it was Jack vs Herc, was more idealogically oppposed, yet at the heart of it, would have been the person that Herc didn't want to lose against the most which meant that him being beaten would have meant that humanity didn't need the gods. Even more so with someone so different yet similar to himself; orphans with troubled paths, but where as one became a God, one became a homicidial maniac despite both kinda both known for killing if one were to overly simplify it.
