The CW's cult show Supernatural is in its final season after 15 years, although considering the current climate, the show might end up getting another year.

An important recurring character on the show from season 4 onwards was Chuck Shurley, who uses the pseudonym, Carver Edlund, a clever portmanteau of Jeremey Carver and Ben Edlund, two of the show's writers, to write a series of books on Sam and Dean, called Supernatural. Chuck started out as an ally of sorts to the brothers until he turned into the big bad. But even before that, was he ever really their friend? Here are the ten reasons why he was not truly a friend to the Winchesters.

Chuck Was Just An Acquaintance

Sam and Dean met Chuck Shurley by pure accident when they were investigating a case. They came across the Supernatural series of books quite by chance and decided to meet their creator.

Chuck was a mere acquaintance with whom the boys crossed paths but he never became someone with whom they hung out or even had a beer. They trusted him given how accurately he dreamt about everything the boys ever said or did. He might even have been something of an ally, but never really a friend.

Chuck Creeps Out The Brothers

When the brothers first come across a set of books with details of every case they have ever investigated, including the tragedy of their personal lives and, well, even the details of Dean having sex, they are naturally freaked out of their minds.

Chuck, too, seems to be creeped out when the protagonists of his book turn out to be living, breathing people. Given that neither the boys nor Chuck are remotely happy about each other's existence, it seems valid to conclude they weren't exactly feeling friendly to one another.

Chuck & The Boys Have A Give & Take Relationship

Chuck was a prophet of the Lord when the boys first met him. Even if he was God at the time, that was never revealed. He had visions about the boys which he wrote down in the form of books.

The boys thought of him as someone they could use to get a heads up on what the future might hold for them. Especially when he first appears, Chuck tells Dean and Sam that he had foreseen a few things there were likely to happen with the demon Lilith who was out to break the 66 seals and release Lucifer from his cage. The boys feel as if they can take advantage of his visions to navigate the crisis. Chuck too, benefits from his association with the boys as they help bring down ghosts at a fan convention. However, the relationship never progresses beyond this give and take.

The makers of Supernatural never make it clear whether Chuck had been God all along or whether he simply became a vessel for God at a later time, before he revealed himself to Metatron and the brothers in the season 11 episode "Don't Call Me Shurley."

However, if he was God all along, well, then he was lying to the brothers and playing and manipulating them from the beginning, which is not something real friends would do.

God Can Hardly Be A Friend

Supernatural has shown how the most unlikely people can come together against common enemies, including angels teaming up with demons, Sam and Dean allying with the King of Hell, and even Satan himself convincing the angel Castiel to briefly become his vessel.

Even God briefly joined the brothers in the fight against the Darkness. Of course, the writers decided to give Chuck-God an altogether not-so-friendly arc after that, but even without that, the brothers having God on speed dial would have been way too much even with all the mind-bending stuff for which Supernatural is known!

God Found The Winchesters Entertaining

The brothers realize at the end of season 14 that God had been using them as a source of entertainment all along. He even goes as far as to tell them that Sam and Dean were his favorite show on earth, quite literally.

Throughout the series, Dean has referred to God more than once wondering how he could be okay with all the horrors across the planet. While Dean had questions for God when they finally met him, Sam looked like a star-struck teenager. All this goes on to show that the boys were ready to believe in the goodness of God, albeit the doubts they had. However, once God told them that they had been a mere source of entertainment for him all this while, any ounce of trust in him would have evaporated then and there.

Chuck As God Loses All Humility

The hapless Chuck Shurley who was fond of liquor and seemed completely befuddled by the epic forces fighting around him, quickly turned into an arrogant, egotistical man as soon as the big reveal came.

Chuck's transformation into God with practically zero humility naturally did not endear him to the brothers. Although he still appears to be a bit laidback and loves his guitar, he is no longer the miserable writer of an underground cult series but a primordial force with a quick temper and unimaginable power.

God Killed Jack

In the final moments of the season 14 finale, right before he was set up as the main villain of the final season, God killed the Nephilim Jack.

When Dean was unable to pull the trigger of the Equalizer to kill Jack, God felt cheated out of a good story. He then killed Jack himself with a snap of his fingers, right before Sam shot him with the gun and he opened the gates of hell. Killing Jack was never going to make him a favorite with the Winchesters and Castiel.

God Put Sam & Dean Through Hell

Irrespective of whether Chuck was God from the time he met the brothers or not, he is God now. Period.

And God has put the brothers through hell, in every sense of the word. From being on stand-by as their mother got killed off when they were kids, the entire showdown with Azazel and the gates of hell, Sam chugging demon blood, the loss of most of their friends and allies, Dean being dragged into hell, the Apocalypse, and then, of course, the fight against the Devil, God hasn't exactly been a friend to the boys. Rather, he has sat back and let them fight tooth and nail to save the world.

God Is An Antagonist On A Rampage

Given that the brothers have fought everyone from the King of Hell, and the Leviathans to the archangel Michael, the Darkness and even Satan himself, it is no surprise that the show would finally end with the brothers fighting it out with God himself.

Chuck is now the primary antagonist of the series, destroying universes as he seems to be on a rampage. At this point, he is a villain, an enemy that Sam and Dean have to defeat or at least die trying. There is no question of friendship between the three of them.
