Careful here… while I agree with your anger, you're using the same language used to dehumanize vulnerable populations. Everyone, including horrible people like Steven Miller, deserve basic human dignity. They deserve fairness, due process, and every human right. But unrepentant fascists don't deserve our attention, our sympathy, forgiveness, or reprieve from justice (repentant ones are more complex and not addressed here).
To treat them as less than human is to risk becoming like them. When you fight monsters, you must take extra care to avoid becoming a monster yourself, after all.
