This really doesn't hold with what we know of Marika.
We know she originally tried to make a global utopia and then succeeded for some time before the Erdtree started to age and lose its virility (the Blessed Dew Talisman tells us this for example).
And we know that she had the sentimental nature to go back to her little hovel of a home village and cast a healing spell over it and leave a trinket of her hair by the village elder she left behind. Probably when she was abducted by the Hornsent.
Together these demonstrate that Marika really isn't some pure lover of violence for its own sake. She's just extremely low empathy when something interferes with her goals.
The Giants posed a threat to her new Erdtree. So she had them all killed and their flame sealed away. The Hornsent were champions of the Crucible and had tortured her people for centuries. So they were wiped out.
But this didn't just apply to enemies, but her own family. Messmer was sealed away because he was a potential danger to her tree. Mohg and Morgott being thrown in the sewers is basically just fantasy racism from her, so it doesn't have a point other than showing her trauma from the Hornsent.
The ability for the Lord to be killed and replaced is important, not as much to Marika as it is to her daughter Melina. Which is why she lets you get away with being a Dung Eater fanboy, because even if you curse the world, someone will eventually take your head and usher in a new era.
For Marika herself, this is partially relevant, but she really just wants you to kill the Elden Beast. That is as far as her Lord is necessary and she'd have preferred Godfrey over the player anyhow. Because she actually liked him.
For the bodies around her at her ascension, she probably slaughtered all the Hornsent that were spectating on her ritual where they were trying to make her into their Goddess.
And then she instead claimed that power for her own self. That being her 'betrayal' of them.
