Yes of course, as a fact we kill something every day, in fact we must KILL to eat. I am under the impression you are confusing “KILL” with “Murder”.
It is not a SIN to kill, for we must KILL to sustain life and the living, and that only the (“soulless”) Animals and plants are killed. A Human can only be killed by the Animal, accident or mechanism, disease or illness, However, a Human can only Murder a Human, or be Murdered by a Human in ancient times before Religion, WAR or Army, “, Thou shalt not Murder” for it is a “SIN” to waste the life of a (“Soulful”) being as these are the whole consciousness of all things living, a common understanding before the “Gods” and (“Atlantis”).
Today " Thou shalt not kill", that in its self is a direct condition to the necessity of LIFE and the living for we MUST Kill. we are not Murdering plants! However, religions are a fallacy I will not get in to here, but make the point, that It has been INVERTED from the TRUTH unto a LIE for the sake of POWER and Authority by the Priest, King and their Army!
Lastly a summary of what is “Soulless” and “Soulful”. The “Soulless” Not born living such as the Seed and Egg, while the “Soulful” are all life born living, just think how many “Murders” are committed daily according to this understanding and reality. Satanism and blood sacrifice of the soulful thing that you and I eat, Also a Sin in ancient times (“Hence Sheep, Lamb, Cow and other beast having “Mystical” value” sacrificially, Spiritually), Some may ask about “chicken” but only in Voodooism, Sorcery and Witchcraft for the material thing, be it blood, feather or bone, etc. In Fact, we had a Very Specific understanding of this thing before ever we ate “Meat”, a side not to that, is that they have covertly forced and continue to manipulate Humanity to participate in there ritual, according to these ancient understandings, Truths and realizations we are in fact Cannibal, we are in fact eating our own kin, even if unaware and unknowing for our ignorance and misunderstanding, it helps keep Humanity and the HUMANS brain in the Primal by “toxicity” of Both Biology and Synaptic “Frequency”.
