Ah okay I see what you're saying James. You don't believe discussing who is a bad father since there are no negative consequences of it, no one tried preventing or stopping it etc. Yes it's it's completely true, but what we are talking about and judging are the actions of the individuals themselves not the consequences or lack there of in this case.
Okay, then let's look at this from a different angle. We are judging these parents by our own standards of how a parents should be. That's a hard thing to use because it's using real world standards to use in a fictional world. How many parent child interactions do you see in the world of Naruto? Not many.
Let's make this a little more fair. Let's compare Sasuke's parenthood and Naruto's to the other adults and parents in the universe that we know of that exist. First we will start with the base:
-Sasuke's fatherhood is basically him being neglectful, not being around, and at even one point being so indifferent he threatened his own child.
-Naruto's fatherhood is a little different with him being there, but also not being there. He is a workaholic who doesn't spend time with his family and when he does it is usually because of moments where they are getting in trouble. When he does does act like a parent, it is in the most pathetic ways but lecture and telling them to endure.
How many of the other Konoha 11 do we know that are shown their parent hood? Very few actually and I mean extremely few like only 1.
-Rock Lee is shown training with his kid and while it is not much I can easily say that this shows how committed he is to his son's life Metal Lee (Oiy, still a cringe name. Sorry, Rock, but it is.)
There are still others
-Hashirama was a father, but we don;t know the relationship with his own child. However, we do know he was apart of Tsunade's life and made a huge impact because she picked up traits from him such as the gambling. Now while that might seem like a bad habit to pick up as a trait it does prove Hashirama played an important role in Tsunade's life.
-Hagoromo or Sage of six paths parenthood is a dominate thing shown in the series and how he was with his two sons. He basically praised the one and neglected the other and the sons seemed to always be at ends with each other. Maybe because they had huge shoes to fill, but I could argue Hagoromo played favorites and even himself mentions how he failed in certain aspects with his kids. Now I can't say this makes him a good or bad father, but at least he admits he messed up as a father sometimes. (Funny how the mothers play no role in any of this)
-Might Dai is Might Gai's father and he is by far the most respected father figure in the whole series. He never treated his son like crap and actually influenced him to never give up just because of a few setbacks. This in turn allowed Might Gai to teach his own son pupil to do the same way and in turn Rock Lee became the same to his kid. This is probably the most detailed version of a father/son lineage I have ever seen. (Come on, Might Gai might as well be Rock Lee's father at this point. If Salad can take on traits of genetics from like god knows how many people, then there is not excuse or reason why Might Gai is not Rock Lee's child. Maybe Might Gai doesn't know Rock Lee his his own kid, and he is certainly stupid enough not put two and two together, but come on. One drunk binder later and I can see it happening. How interesting would that be too? Gai not knowing he is a father, but actually being a better father than anyone else.)
-Kakashi's father, I forget his name, has been shown to be a parent too. He looked like a parent who tried, but he just couldn't seem to get being a father down. When he died in what people believe was a betrayal, His son resented him, but Kakashi found out the truth, he loved his father more and finally understood everything. This might seem like the real world parenthood in which most often than not, kids are rebellious and don't understand their parents. This does not necessarily make him a bad father, but that their relationship is a bit slow. Only when Kakashi became a man did he finally understand.
-Fugaku, Sasuke's father. (see below)
-Minato as Naruto's father (also see below,) but want to go in deeper with this. This is a father how never really got a chance to be a full fledged father because of Obito. So, we can;t really judge Minato's fatherhood. However, what makes me ponder it all is how much of an influence Minato still was despite not being in Naruto's life for most of it. And I mean positive influence like supporting him, leaving him stuff, leaving the messages and in a way still watching over him. Yeah, he only briefly got to meet him, but he did more in that time than most parents I have seen in this series. Even Kushina as well. They spent so little time with their son and yet they made this huge impact on him. They loved him and left these pieces of their souls inside to come out and one day explain to him. Like I said, it is like comparing Superman and Naruto like this. So I could say that Minato is a good father because despite everything, like death, he still tried to be a part of his son's life. This doesn't translate well to Naruto though because Naruto seems almost annoyed being a parent given what we have seen of him with Bolt.
Everyone else we either don't see them being parents or they never got a chance to because they died.
I am only basing off what we have in the series and I can't base off my own experience because I am not a parent yet. So I can't give a full spectrum. Comparing the parenthood to other parents in the series.
So compared to other parents in the series, how bad is Sasuke and Naruto?
But Sasuke did have a father figure. His own father Fugaku. He should already know what it takes to be a decent parent based on being raised bu his dad
But his dad was overcritical, never gave him attention, and valued Itachi above him. This is why when Sasuke talks about bonds, it is the bonds with his brother, not with his father. This is unlike Naruto who had a strong bond with his parents albeit brief. Yeah, he only got to see them one, but he got more value and love and care from his father in those brief moments than Sasuke did his entire life.
I'll give the perfect example. Naruto actually cried and loved his father when he realized he finally met him, knew him, and then he had to leave. That is powerful. It's like Superman meeting his own father Jor-El through the holograms to which Jor-El said "We wanted to be there for you, but we couldn't. We had to make the toughest choice out of our love for you" and Kal-El/Superman understood this.
When has Sasuke ever thought about his father or held him in respect when he grew up? Does this make Fugaku a bad father? No, but it means he never had a huge influence over Sasuke's life. Minato was a bigger influence on Naruto's life in even the most minor ways that Naruto never knew until later.
