OK...I just watched the video. I can understand the outrage...it was premeditated...and not a joke. You see her go up to the cat...stroke it...look at the bin...look around to see if she could get away with it...and then putting in the cat, closing the lid and walking away fast...no laughter...not going back to take the cat out and play with it and laugh at its momentary surprise and to console it....it was no joke.
It was..and is not...about the cat. Neither with her...nor with the outrage from people from around the world. It is in the way she used affection to ensnare an innocent being...how she dispassionately picked up the innocent...and loving (the cat's response to her stroking was in giving love back) sentient being...planning her act...looking around...thinking about it and her odds of getting caught...then throwing it away...in essence betraying love and goodness...a sacred bond that should be there in all beings...she, condemned it to death in her mind...the trash gets compacted.
It was a predatory act of dominance on a completely innocent and defenseless creature....through deception...that unglued many. It is the method of operation of Pedophiles...that is what struck so many to heart (not that she is one...just that the method is so disdainful).
Remember...for a woman...and yes...especially bad for a woman to do so because in almost all societies the woman is the chief caregiver of children...to not have basic morals to prohibit her from doing evil against the innocent and helpless (children) is to place fear into the hearts of all where trust must be a given. Women cook the food for the family...take care of the children...there is no stabilization of society if morals are not clung to. A woman in trust of the most sacred bonds who cannot be trusted to not poison the food or to not abuse children when no one is there to catch her signifies that either she is evil...or that perhaps many more would do such a thing in the absence of authority. To NOT have outrage is what would be upsetting. The outrage is directed appropriately...now any act upon that outrage would be unjustifiable...but in the words of Chris Rock...I would understand

.
I also agree that there is no similar outrage for far more heinous acts. Rarely, though, are the acts shown with such clarity of purpose...the premeditation...the deception using love and receiving it in return...the chance to not do it...and rather she looks around to assure she wouldn't get caught...and the act...then the scurrying away. It was in the pure and raw evil of the act...not the result.
That is why they have banned any graphic portrayal of late term abortions in public in the U.S. (available under certain circumstances...wink..wink) - were people to see the actual effects...they would not accept it (just to clarify...early term is understandable - 1st trimester...or even better...morning after pill...best of all...protection or abstinence until certain you would take care of any baby that could come about).
That is how we can eat meat...we are not exposed to the slaughter...usually. When films have come about...procedures are changed to ensure ethical means are used..wink..wink. There is a purpose to eating meat...we are removed from the act...different.
Animals, especially pets...represent the pureness, innocence, and all that is supposed to be good in this world....it ties into our Paternal...and woman's Maternal instinct. They are just as our children. I used to have dogs....they were family...I could have easily killed another human who attempted to kill any of my family...of course, I would have had to say a human life was in danger had I acted...but that is easily stipulated...I would have been between the attacker and my dogs...he would have had to have gotten past me with a deadly weapon. Anyway...you see my point. We have these instincts because pets are so much like children...pure, innocent..loving...trusting...all that is good. It is an assault upon all that is good by evil...
Yes...she probably won't be doing that again...however...I believe..only because she knows she is going to be watched. You can bet the authorities are researching any unsolved crimes in the neighborhood...especially against the defenseless.
Death threats are overboard...and stupid. She deserves what the law allows...nothing more. She also deserves no complete trust from those around her...ever more.
