What I know is that kill and murder are quite different concepts. Why move the goal posts? Nonetheless, if killing is what you want to talk about then yes God has always allowed killing and killing is morally neutral when done for survival. We must kill in order to survive. We cannot survive without killing so if God were to pronounce killing as morally bankrupt, we would simply have to engage in morally bankrupt behavior as we cannot cause our bodies to refrain from attacking bacteria and viruses nor are we inclined to stop eating and drinking causing ourselves to starve to death or die of dehydration. The fact that God told people to kill does not mean that God told people to murder. If God were to all of a sudden decide that from now on murder would be a fine thing, then murder would be morally upright. Just as he decided that from now on eating pork would be a fine thing but previously, He had decided that eating it was morally bankrupt. The rules are His and He can change them as he sees fit. God is immutable and unchangeable, but we humans are not therefore the rules we are to follow from God are structured by God to fit where we are at in our development. They are not imposed upon God by some outside force that requires a standard to which He must adhere.
BTW, If you want to engage with yourself in conversation by pretending that the quotes you pull out of your nether regions are actually from someone other than yourself perhaps you should converse with the mirror? I have answered every question you asked, and you have ignored every question I have asked. That being the case, I will return the favor and ignore any further questions you have until such time as you answer at least one of mine.
