For one, how would a child raised in one part by Fey and the other part by Kratos grow up to disrespect his parent? 10-year-old Atreus would have never insulted Kratos. So what happened 4 years later for him to do that when all this time he got closer to his father who taught him discipline, focus, and hard work? The way he behaves doesn't even make sense with what Kratos had been teaching him for the past several years prior to Ragnarok nor how he was as a kid.
I'm gonna go ahead and say that you don't have kids and haven't spent any significant time around teenagers.
They rebel... it's in their nature to do so.
Atreus never knew raging Kratos so why would that influence him in the slightest?
Of course he did. Kratos is his father. He knew about Kratos's past with all the Greek Gods. It's wholly implied by the dialogue in which they touch on his relationship with Zeus and the rest of the Greek Pantheon.
Kratos would have told Atreus his entire life story by this point.
That he's thick-headed and impulsive is fine. That's just the way he is. That he's disrespectful and entitled is nonsensical based on his environment, parents, and background. As if Kratos would ever raise a kid to be disrespectful.
Again, you really haven't spent any significant time around teens, haven't you. They're ALL disrespectful and entitled, irrespective of who their parents are and how they were raised.
Atreus is a god and knows he is. So, it's going to magnified to the nth degree for him.
I never said that. I said that with the way the new series is written, they actually need to write believable characters. With the original series, they didn't need to because as Jaffe so eloquently put it, it was pulp. There was no higher purpose or breaking down of characters or intentional character arcs and all of that. Atreus does not need to be likeable. He needs to be believable
Well, he is believable. It'd just that you're measuring him by some entirely unrealistic, entirely idealized version of how teenagers behave. Go spend some time in a middle-school as a volunteer and you'll see just how believable Atreus's behaviour is.
