Everything living kills everything in sight for resources. From viruses to civilizations. To some extent this can be moderated, or for a time some optimizations

Everything living kills everything in sight for resources. From viruses to civilizations. To some extent this can be moderated, or for a time some optimizations might result in even less destruction, but this is the way this world is. Killing is rational in a sense - for some subset of purposes, in context of some subset of environmental pressures, both of which change constantly, and often faster than adaptation to kill does. Accept this. It will not ever change.
