Oy. We have a plan for the slavers. Part of our intel prep was finding the very worst ones, the ones even other Tyroshi gave side-eye to for being too torturous, or the ones who were the very best at the slave trade. Those will be the examples to satisfy the newly freed slaves, when they see the most hated and feared magisters executed for their excesses, their property seized, and their family cast down from nobility to mere freemen.
The second round will be those magisters who think they can be like Pentos, as long as they keep their slaving reasonable and discreet, things can return closer to "normal," right? And then they're hanged, their property seized, and their family cast down.
And then at some point there is going to be a third round, where we have to hang freed slaves who are revenge killing former masters and their families. This is inevitable, and unavoidable, but if we keep an eye out for it and stomp on it at the first opportunity to prevent a rash of such killing occurring. Because freemen killing other freemen is murder, and we are not bringing vengeance, we are bringing
law and
justice.
Vengeance is merely self-satisfaction. It helps no one. It doesn't help those wronged, as you stoke the fire in their hearts. It doesn't help the innocents who will be killed in the aftermath for the crime of being born to a magister's family. It doesn't help keep the bloodshed to a minimum when we move on the next daughter, because they will rightly think we will engage in a pogrom against the freemen of the city, and they will make any pact or deal they can in attempt to keep their lives.
@tarrangar you are literally proposing to sacrifice people's lives (in Tyrosh and beyond) for the purpose of feeling good about it. It brings no benefit, and no real peace, and requires weeks or even months of Viserys's attention. Time he could be using to actually help people elsewhere in the world by stopping evil today, instead of obsessing over wrongs of the past.
