There are people who torture and kill cats for the fun of it on holloween. If we lived in a lawless society, I think it would be more fun to find the people that do this and torture and kill them.

Would I be wrong to do that? Why?

There is definitely something wrong with this reasonning and I'm surprised that no one pointed it out. It's basically that your moral stance makes no senes. You've stated that you don't think that as there is anything wrong with eating meat.(let's assume that you're eating meat yourself)
If you think about it, that means that you have nothing agaisnt killing an animal for your own enjoyment, since you could be a vegetarian.
So basically you want to kill and torture people who have killed and torture a cat just for they own pleasure.
According to your ethics though, there is nothing wrong with killing a cat for fun, so the only reprehensible thing they've done is torture a being that you would have not problem killing.
Of course you can argue that it is bad ennough that they deserved to be severly punished, but given your ethics the sentence seems harsh.
Furthermore, you have to ask yourself why you have no problem killing an animal but you don't wan't him to suffer.
Since you don't want it to suffer, one can assume that he reallys feel the pain abd that he is not just a living machine, that he has a conscience..
But in that cas shouldn't you be vegetaraian?
