Better to be scorned by Balon the Brave than beloved of Euron Crow's Eye. (The Prophet, AFFC)
I'm not getting into whether Euron is even capable or love (though he does refer to Aeron as a "loved one" in TWOW), what interests me in this sentence is the way Aeron's views of his brothers contrasts with his views on what brotherly love means.
Aeron seems to have a great admiration for Balon as a ruler, he sees him as everything a king was meant to be, the man who restored some of the former glory of the Iron Islands, a man that Aeron even considered to be one of the pillars in his life. On the other hand he despises everything Euron represents, both to himself —given the abuse he suffered— and to the collective people of the Iron Islands, their way of living and specially their religion considering Euron's "ungodliness". But love seems to be something he associates with Euron, rather than Balon. Which is interesting because he understands very well that he was abused, he never sugarcoats anything, he seems certain and righteous in his hatred for the Euron and doesn't justify his brother hurting him. Not like he justifies Balon's scorn ("I was weak and full of sin, and scorn was more than I deserved"). And yet, he felt loved (a very twisted sort of love) by Euron in a way that he never felt he was by Balon. To Aeron scorn can't coexist with love, but abuse can. It's the kind of mindset that makes sense when you're part of a society whose values are mostly built on violence.
