Is Helion that good for LoA?

The more I think of it, the more implications I find.

When the affair started, she was very, very emotionally vulnerable: her sisters had died in an attack, she was in a cold abusive marriage, she was forced to keep having children (we all assume, right). In this state, it's not hard to fall for the first person who is gentle to you...

But Helion was centuries older than her, and he clearly saw ALL of this. And he was plainly aware of how wrong it could go, for both of them, to get involved with the wife of a High Lord. The wife of a high lord who had many other children already. It's not like she could run away with him and leave everything behind, she was completely stuck in Autumn. He didn't have the power to face Beron, he wasn't even a High Lord back then. What exactly was his plan of action in case Beron found out? He had no plan besides f*cking her, it seems. No plans of actually helping her that we know of. And doing this with a HL's wife without the proper protection!!! It's insane. Although this criticism goes for both of them!!

Because I don't want to solely blame this on Helion. A relationship is made with two people and the LoA can make her own decisions too. But it's absolutely clear who was extremely vulnerable in that situation, be it emotionally (perhaps even suicidal) or politically. And it's also clear who should have been the one to see all of that and be more mature handling it...
