I actually ordered the book this is based on so I'll be reading it then I'll report back.

I didn't quote the whole thing but the wiki writer also says "Nietzsche saw this as a contradiction"

I actually think it makes sense. It's literally exactly what the left is doing. They've embraced that contradiction. We know their values and beliefs don't actually bring good for everyone and they are inherently destructive. They simply set the stage for a new master morality to take over.
