Is it legal to kill someone?

[Scat]

Sometimes it doesn't matter whether it's legal or not... just do it if it is necessary...

Killing, to cause the death of an organism, or the act of doing so.

Murder is the unlawful killing of another human being with "malice aforethought",(although i dissagree with unLAWfull, cus i think man made laws are stupid. because what might be legal here might be illegal 1mile down the road.) also note manslaughter is considered without "malice aforethought". so manslaughter and murder are the same imho.
my definition of murder should be: is the immoral killing of another living organism. yes killing a cta jsut cus you feel like it is murder. killing a cow cus you need sustenance is not imho.

my views of what is murder and what is not is more of a religious matter.

but then again your asking if its legal. so by defintion when is murder/kiling legalsource wikipedia):

* Unlawful killings without malice or intent are considered manslaughter.
* Justified or accidental killings are considered homicides. Depending on the circumstances, these may or may not be considered criminal offenses.
* Suicide is not considered murder in most societies. Assisting a suicide, however, may be considered murder in some circumstances.
* Capital punishment ordered by a legitimate court of law as the result of a conviction in a criminal trial with due process for a serious crime.
* Killing of enemy combatants by lawful combatants in accordance with lawful orders in war, although illicit killings within a war may constitute murder or homicidal war crimes. (see the Laws of war article)
* The administration of lethal drugs by a doctor to a terminally ill patient, if the intention is solely to alleviate pain, is seen in many jurisdictions as a special case (see the doctrine of double effect and the case of Dr John Bodkin Adams).[20]
* In some cases, killing a person who is attempting to kill another can be classified as self-defense and thus, not murder.

also abortion is legal which imho opinion is murder.

wel to answer ur question. its a bit vague mostly killing is "unlawful/Illegal. depending on your jurisdiction. do without knowing the means of killing/murder. and what part of the world your from your question can not be answered
