Obviously not. The murderer may get a kick out of killing people ( although many murderers will deep down inside NOT feel good about it, they live in conflict with themselves). The societies witnessing the murder will be shocked (and this applies to any society, at any time, from the early hominids to nazi Germany) because deep down inside our “altruistic genetic make up” tells us murder is despicable. (Society will punish the murderer; either with a prison sentence or a death sentence. A death sentence is however also murder, and then a moral discourse starts: society will struggle to find the balance between our (genetically programmed) levels of altruism/ egoism).
