Except in the cases hereinafter excepted, culpable homicide is murder, if the act by which the death is caused is done with the intention of causing death 2ndly. If it is done with the intention of causing such bodily injury as the offender knows to be likely to cause the death of the person to whom the harm is caused. or- 3rdly. If it is done with the intention of causing bodily injury to any person and the bodily injury intended to be inflicted is sufficient in the ordinary course of nature to cause death, or- 4thly. If the person committing the act knows that it is so imminently dangerous that it must, in all probability, cause death, or such bodily injury as is likely to cause death, and commits such act without any excuse for incurring the risk of causing death or such injury as aforesaid.
When culpable homicide is not murder.-Culpable homicide is not murder if the offender, whilst deprived of the power of self-control by grave and sudden provocation, causes the death of the person who gave the provocation or causes the death of any other person by mistake or accident. The above exception is subject to the following provisos:- First.That the provocation is not sought or voluntarily provoked by the offender as an excuse for killing or doing harm to any person. Secondly.That the provocation is not given by anything done in obedience to the law, or by a public servant in the lawful exercise of the powers of such public servant. Thirdly.-That the provocation is not given by anything done in the lawful exercise of the right of private defence. Whether the provocation was grave and sudden enough to prevent the offence from amounting to murder is a question of fact.
(a) A shoots Z with the intention of killing him. Z dies in consequence. A commits murder. (b) A, knowing that Z is labouring under such a disease that a blow is likely to cause his death, strikes him with the intention of causing bodily injury. Z dies in consequence of the blow. A is guilty of murder, although the blow might not have been sufficient in the ordinary course of nature to cause the death of a person in a sound state of health. But if A, not knowing that Z is labouring under any disease, gives him such a blow as would not in the ordinary course of nature kill a person in a sound state of health, here A, although he may intend to cause bodily injury, is not guilty of murder, if he did not intend to cause death, or such bodily injury as in the ordinary course of nature would cause death. (c) A intentionally gives Z a sword-cut or club-wound sufficient to cause the death of a man in the ordinary course of nature. Z dies in consequence. Here A is guilty of murder, although he may not have intended to cause Z's death. (d) A without any excuse fires a loaded cannon into a crowd of persons and kills one of them. A is guilty of murder, although he may not have had a premeditated design to kill any particular individual.
