What adds insult to injury with Daenerys’ death is that it doesn’t really have any kind of larger consequence within the context of everything that happens after it.
It’s just the death of another tyrant.
Grey Worm is really the only person left speaking for justice on her behalf, and his voice is all but drowned out by those belonging to the most powerful people left in Westeros.
As for Jon Snow, Dany’s murderer, he was sent back to Castle Black and the Night’s Watch – which was tantamount to sending him to live at his preferred home with his best friend and his dog.
