to be fair , MAJORITY (not all) of people you see get beat up on the internet probably did something to provoke that. Not only that, they usually recover in the next few days. Dogs dont really provoke such hate/abuse and they usually live with the abuse the rest of their lives unless they are rescued.
so cant really compare the 2 situations
hitting someone cause they said some foul shyt about your family or hit someone you know = we not really gonna blame you for that
kicking your dog when you get home from work and had a bad day, even though the dog probably greeted you = that person a piece of shyt
