Why is homicide bad?

[gdnp]

Societies do not punish some homicides and accept others to "improve the human race", as you wrote here:

Of course they do. They may not speak of it directly, but they allow/encourage homicides that are "good" and punish those that are "bad". Thus leading to an environment where society can flourish.

It isn't. Go ahead and kill somebody.

No.
Societies "encourage homicides that are good" (if you can call capital punishment or wars this way), as a way to protect themselves, not as an improvement of the human race.

Which I did not.
You are obviously trolling.
