That's stomach churning footage of those chambers. Have we always been this evil, or are we becoming something new?

I am not sure why you think that this sort of behaviour is new?
The methods of torture devices centuries and millennia ago are just as horrifying as what you see here. Crucifixion for starters. Brazen bull. Breaking on the wheel. Etc.
No, this isn't new. What is new is that this is more rare than it used to be. (At least, I think/hope it is. I might be wrong). We just need to continue on that path.
