Historically, humanity has shown tremendous creativity in finding every possible loophole, rationalization, and justification to ignore those commandments. Animals kill for food, and to protect their territory, which suggests killing can be a normal, natural part of life. But humans are civilized. They’ve supposedly moved beyond mere instinct. Yes, animals kill. They also eat their young, but if you suggest a human mother do the same, people tend to react poorly. Animals will happily interbreed with their siblings as well, but that’s frowned upon among humans. (Though some of them do it anyway, and many others fantasize about it.) The behavior of animals does not provide moral justification for human beings to do the same. Is killing ever a moral choice? What if the personal decision to avoid inflicting harm leads to a greater evil? Countless writers have penned tales of traveling back in time to kill Hitler. Would such a murder be right if it prevented millions of other deaths? Isn’t doing nothing while a vampire attacks my loved one a greater crime than destroying the vampire?
