There is...
...but there is in people who are not that stable in the first place.
As you and others have said.

On a related note....most spanking videos are kinda tame and use lots of red rouge. It is acting.
However...I saw two that were as real and violent as can be. No faking any of it.
I hope the two SOB's are in jail now.
To complicate the issue, there are some women that want and seek that level. I have met them.
What they wanted was not fun playtime.
No thanks.
