show their faces on public without consequences.

Aren't they still hiding their faces?

There is a huge difference between not fearing them and saying they aren't humans.

There is also a huge difference between killing them (which wasn't even objected here) and saying they aren't humans.

Acknowledging that evil people are in fact people isn't softcore, it's a baseline necessity to critically examine one's own actions and beliefs for moral flaws. If you believe yourself to be a good person, and you believe that only evil people do evil things, then you give yourself a pass on everything you do. That car crash can't have been your fault, because you're good a good driver, and only bad drivers cause crashes. That homicide wasn't manslaughter, it was self defense. Only bad people commit manslaughter. Everyone knows rape is evil, and you're a good person, so there's no way that sex you had was rape. If someone says otherwise, they must be lying or mistaken.

Those vermin need to know we don't fear them,

You clearly do though.
