The Artisan, I honestly feel you have a massive misunderstanding of Cersei as a character if you honestly think she cares more about power than her children. This is one of the main points that have been drilled into the audience's head over and over and over. Like, I honestly have no idea how this is even a thing you're willing to dispute, and because you have this misunderstanding, you think every act of Cersei protecting her children is not actually her giving a shit about them, but just her wanting power.
You think she thought she would be fine when Robert found out about Joffrey and the rest, and that the only reason she killed Robert was not to save their lives, but to put Joffrey in power. Pretty much all the Targaryens were murdered off, and he still kept trying to kill Dany in Essos, even though she didn't do shit to him, but you honestly think she thought she would be fine with Robert coming after her? That's preposterous, there's no scenario there where Ned would've realistically being able to protect them.
And what innocents? All the people in Blackwater that died, all the people that war causes to die, I mean, you shrugged that away with "it's war", yeah, tell that to all the people who are now dead because Margery wanted to be the queen.
