Unpopular opinion about Daddy Aetos

I've been diving into the fandom, both here and in fanfiction, and it seems widely accepted that Daddy Aetos is an abusive father for two reasons: the fact that he is indeed an abusive asshole in IF and apparently, RY said Dain is a parallel for people who are groomed (but didn't say by who).

I don't think Aetos is an abusive father more than say, Lilith. He was probably not the best, but also not the kind to completely dismiss his son and have him call him "father". Why? Because the only scene where Dain and him interact is a scene where Dain publicly calls him "Dad".

Now you'll tell me abuse can be more subtle and be hidden in kindness and closeness, and I agree. But one thing an abusive parent does is to have their child emotionally dependent on them, constantly seeking approval, and having a hard time breaking the cycle. Which Dain isn't. AWhen he discover the truth in IF, it takes him zero thought to say he is the one being disappointed (implied in his dad) when Varrish tries to emotionally manipulate him by saying his dad would be so.

Not to say the relationship between the Aetos men is healthy (the father being capable of disowning his son is a red flag), but I don't think Daddy A is as cold or as manipulative with is son as people think.
