MC you can not be pulling out the power of the protagonist so often like this, your gonna have the whole cast in love with you half way through the story, and their gonna get their hearts broken cause of your love for the villainess
And with this added info, changing other plots isn't gonna change much of the center of what gets villainess killed so something she did, of your trying to prevent her death you should be using your talk no jutsu to talk villainess out of her extreme secret hatred of the fucking peasants
