Brilliant point. I think the answer is quite a few, probably more than not.

How many people went to the colosseums of Rome to see the condemned hacked to death by gladiators?

I won't mention more fresh exhibitions of pain, degradation, and depravity because the denials would obfuscate your point here. But we all know.

But even in sports....People go to Nascar to see the wrecks and pray for fire. All the fighting sports. People hope for injuries in sports played on fields.

And never think twice about it.
