It's not just the fact they killed the dog, it's how and why. They did it for the rather slight reason of stirring emotion from here, in thus killing her only friend at that time, and it's clearly depicted as horrid as it can be. It might not be that big a deal in some other forms of media (notably ones that'd play this stuff for black comedy) but it's clearly supposed to be shown as one of the worst actions in the series, as well as the monsters humans can be. We're supposed to see them as monsters, and therefore, they are.

Never mind their reactions when the dog bleeds out. The show is trying to play them as horrible as can be. The only reason TV Tropes wouldn't accept them is because of their rules when it comes to being a Monster. Really, it doesn't matter what you do, as long as you do it heinously enough.
