That is true but the way euron just showed up and started hacking people, I don't blame them although i'm pretty sure it's the choice of weapon too. Like no, a whip is not going to save you in this very moment.it's so obvious that they left only one daughter of ellaria alive with her. It's a kind of 'karma's a *****' moment for cersei who lost myrcella which was basically her last hope and child. And also ellaria is going to watch another person she loves die which is really sad, I guess.
