I seldom side with animal rights nuts. However, when a disturbed nut executes cats in a bag by sucking the air out with a vacuum cleaner or feeds them to pythons this is something that desrves notice and action.
Unfortunately, abuse of animals is frequently a sign that shows up later in serial killers.
The subsequent snuff film is not unexpected from this moron.
In this case where a person deliberately tortured his victim the death penalty is waranted.
