alt Hacker News> The reason that I am not killing people left and right is not because it is illegal to so but because it is immoral.
And if it wasn't illegal, some immoral entity would outcompete you by killing all of their rivals (including you).
The whole point of the law is to standardize morals so immoral actors don't gain advantage.
Not necessarily. Humans aren't really capable of living entirely solo. We rely on a society - even a small tribe - to provide resources that we struggle to make. We evolved for tribes and tribalism to support our survival.
People who commit murder wantonly are generally untrusted and/or shunned. Being banished is really dangerous, so people tend not to go on more killing sprees even without formal laws
