No, it isn't. I have been a killer all my life, from my earliest youth. I have never killed because of my feelings, for a thrill, but once did just to see if I could hit my victim. When I proved competent to do so I wept at the suffering of my victim, and was inspired to exercise mercy to the fullest degree possible, to kill as humanely as I could manage all my victims thereafter. Indeed, I sought to personally kill as many of the dead from whose death I profit (which is the reason I kill, to extract valuable resources from the dead I take for myself) so that I could ensure their deaths were as free of suffering as possible.

I often kill my victims with a blade, up close and personal, by extracting their valuable organs, before I sear their living cells in hot oil, boil them in water, or merely expose them to unsurvivable heat, and eat them. Some I do not, but merely mash them into a pulp and dissolve them in acid. Every fall I participate in the holocaust of sacrifice that is traditional to my people, and seasonally to all peoples in the Northern Hemisphere, though everyone everywhere has similar sacrificial practices, just seasonally adjusted. Other than striving to kill personally as humanely as possible, I know very little about the majority of my victims, but lately have sought to change that by rendering my victims dependent on me for their lives. I seek to raise them from birth, tending to them, nurturing them, providing as safe and pleasant a home for them as I can, protecting them from disease, pestilence, enemies, and any adverse conditions I can prevent, until I kill them. But, even so, I never get personally involved in their lives, never chat with, hang out, or even know their names.

Still, I feel better about killing them and profiting from their death by doing so, and fully intend to spare as many of them from as much of the toxic environment created by our corporate overlords, or the cruel predation and parasitism of the natural world, as I can. I feel this makes their deaths, and dismemberment at my hands, more beneficial to me.

So, just as my beneficence to the produce in my garden is not contrary to my purpose to kill all it's denizens, does not reduce their profitability to me, and being more cruel, or even less nurturing to them, would demonstrably reduce the benefits I take when killing them all, no lack of mercy or compassion for me would be valuable to them in any way. Our humanity is the reason we are merciful, and in no way is reducing or eliminating our humane and merciful treatment of criminals, even murderers, of any benefit to their victims, regardless of what the victims think about that. Our compassion and mercy is always a benefit, not only to society in general, but to the victims of crime particularly, because insofar as we inculcate in successive generations a geas of mercy, of compassion, by our example, we raise less brutal killers, just as I myself demonstrably am.

The reverse is true. Cruelty and lack of compassion for criminals would teach our posterity to be less merciful. To judge and kill without doing so humanely would provide that example to criminals, whom may well be already inherently prone to inhumanity, as they descend to criminality, which necessarily dehumanizes their victims. By always acting with a fundamental attention to mercy, we infuse the acts of even criminals with that example, which they themselves will have learned thereby, and which their deviations therefrom should reasonably be expected to fall far short of the cruelty of criminals whom have not exclusively witnessed such humanity. That compassion for criminals does not depend on the nature of the criminals, but on our nature. Just as our words do not reflect on the audience or topic of our speech, but on us, we who speak them, and from whom they derive, so does our compassion reflect not the crimes of criminals, but on we who judge them.

Demonstrate mercy, that even murderous killers will kill more humanely and mercifully. Raise up a child with compassion and mercy, and they will practice what they know, what they learn from us, all of their days.
