@dlowan,
I didn't say I categorically dismiss intent. I said I judge behavior by its consequences. Sometimes the intent behind a behavior has consequences. And when it does, it will make a difference in my judgment. I just don't think that intent is morally important
per se, beyond its practical consequences.

No, that's not the relevant difference to me. What's done is done. We can't change the past with our reaction to the killings. The only thing our reaction
can affect is the future, and any killings that may happen in it.
Serial killers will kill again
in the future unless we lock them up. That, to me, is the reason that the law ought to lock them up. By contrast, unfortunate drivers will probably not accidentally kill other motorists
in the future, and any punishment we might submit them to will make practically no difference to whether they will. That, to me, is the reason not to punish them, and to merely make them pay damages. The offenders' intent matters to me only insofar as it affects their expected behavior in the future.
Anyway, our digression about intent is irrelevant to the subject of this thread. My conclusion about cat torturers, horse rapists, and pig farmers would be the same even
if I agreed with you about intent. In all three cases, the human acts consciously, deliberately, and with the intent to do it again. And in all three cases, the benefit to the human is trivial compared to the suffering of the animal. In the horse rapist's case it's sexual pleasure, in the cat stomper's case it's sadistic satisfaction, in the pig farmer's case it's so that humans can eat ham rather than smoked tofu. What's the great difference between the human's intent in each case? I simply don't see it.
