If you noticed the difference in how Lady talks about Sparda in the games vs in the Netflix show .

In the games, all the humans and even Lady respected Sparda. but hated demons. Which pushes the idea that you can like one member of a group even when thinking the group themselves are bad.

But in Netflix, they made Lady disrespectful of Sparda just so they could push the plotline that she is unfairly prejudiced against all demons and demons are "not all the same and she should stop discriminating against them"

They couldn't give her the original character otherwise it would undermine the message that they try to push that all prejudiced people are unreasonable because Lady in the original games was prejudiced against demons even whilst still respecting Sparda, but in the Netflix trash show they made her disrespect Sparda so they can push that she was "unfairly " prejudiced against demons. They can't fortham an idea that you can respect individuals of a group whilst still hating the group as a whole. Because if they admit that prejudiced people can be reasonable then they will also have to admit that people can be prejudiced against a group for a good reason .
