Is it wrong to hope for an avenging super pigeon?

Maybe I'm still upset from seeing a poor pigeon this weekend who had its tail feathers ripped out, who lost all of the feathers on its stomach and back, and who apparently had both legs broken, dragging itself along the sidewalk, using its wings to pull itself along to look for food, but this article really pissed me off.

Here was my response in the comments section:

Hey, why not go even more local and eat dogs and cats? I mean, they're right there in our own living rooms! Sigh... As both an unabashed admirer of the pigeon and a vegetarian, I don't think I'll get much traction in responding to this, but just because you can eat something doesn't mean you should. Pigeons are extremely intelligent creatures that can identify abstract art and saved our (Allied) behinds in quite a few WWII battles. But hey, who am I to argue? Humans killing and eating everything in sight has worked out so well for the planet thus far.

I don't understand why people are so cruel.
