> Why is it wrong to kill another man?

"Why" implies to me that there is or should be a rationale. Our culture stores a lot of behavior and spreads it by the means appropriate. Some need rationale most do not.

Killing feels evil and is considered morally wrong. But in reality mankind, like many species, decided at some point, that killing its own should generally be avoided and is therefore allowed only under very specific circumstances.
