Yes, but why is it wrong? Why is killing a homo sapien wrong as opposed to killing a pigeon, which is right.
Unfortunately, for English at least, this is where the conversation splits. "Murder" is defined as humans killing humans, and almost always with the subtext of "intent" (accidental killing is rarely referred to as murder). "Killing" is anytime you take a life, and it doesn't have to be a human or an animal to be killed either... Or even living, now, that I think about it (kill the power, kill the music, etc.).
Kinda semantical, but I honestly think we make this distinction for the sake of intelligent conversation. We have to have words somewhere 🤷
So, referring to your original question, were you looking for why "murder" or all "killing" is wrong?
