sad or distubing moment in Animal Farm.

the first thing I thought that was sad was when the pigs confessed to Napoleon and had their throats ripped out. that was also a grusome moment because the thought of having your throat ripped out must have been painful enough to kill ya', and i guess the ones who confessed died because of the massive pain that was inflicted to them. Imagine growling vicious dogs coming at you at a somewhat like light speed with saliva bearing shark like teeth coming closer and closer to you and the next second, all you see is a black hole and a little tiny light and you feel a warm drippy sensation on your side or belly or whatever you fell to. thats what i was thinking in my head when i read that part in the book.
In chapter nine, when boxer healed up his hoof and started working again to repair the windmill, I thought he was crazy to do it all by himself with no help of others. Then i kinda expected boxer to collapse of somthing but not his lung i didn't expect that. It's hard to visualize a horse with a busted lung and still be alive, shouldn't he have been gasping for air, i thought that was kinda weird for a horse having an ill lung and not struggling for breath. i mean it ould be logical, but i can't belive napoleon would take his own loyal workers and just send him off to his death. its just a creul thing to do, that was the distubing moment, if you think about it, you could actually see the look on boxer's face and all the animals they would either look sad or enraged at napoleon for doing this to such a strong but brain dead work horse.
