Human v. Dog. I cannot believe this is even debatable. You may believe in capital punishment. That’s a separate issue. But to equate human life with a dog? Basically you are saying the property of another –dog — is more valuable than a human.
No, I’m saying that the lives of some humans — serial killers, genocidal psychopaths, people who prey on the aged or very young — have negative value. Would I throw the switch in the electric chair? Probably not. Do I support the death penalty? In general, no. But I think that there are many non-human life forms that are worth more than certain sorry examples of humankind.
