That's a pretty comprehensive list of reasons to kill. Imagine if we utilized the same 56 reasons and resulting consequence to deal with human ailments!!!

-we wouldn't have the healthcare crunch that we do,

-there would be empty beds in psychiatric wards,

-we could just euthanize anyone that had a cold that showed up at hospital emergency wards,

-parents could do away with their children if they cried when left at daycare or if attempts at potty training failed,

-Attention Deficit children would be a thing of the past as would people with MS, Asthma, Chrohn's Disease and on and on.

What a neat and tidy world it would be....wouldn't it?

One other thought....
Humans that abuse, maim and kill animals get very light judicial reprise, but animals deemed "aggressive to cats, dogs, humans" die for their crime.
