Homicide vs Murder: Legal Meaning, Gravity of Offences and Legal Ramifications

What is the Difference between Homicide and Murder?

Homicide is a broad legal term for the act of one person causing the death of another, encompassing both lawful and unlawful killings. In contrast, murder specifically refers to the unlawful and intentional killing of a person with malice aforethought.

Understanding the Legal Distinctions: Murder vs Homicide

Homicide vs Murder: Homicide and murder are often used interchangeably in everyday conversation, leading to a common misconception that they refer to the same act.

However, in legal parlance, homicide and murder have distinct meanings and implications. Recognising these differences is essential for a nuanced and informed discussion about legal responsibilities and ramifications surrounding the taking of human life.


Homicide is a comprehensive term used in law to describe the act of one human being causing the death of another. It is not always deemed illegal, as it encompasses all instances of someone killing another, regardless of legality or intent.

Homicide is categorised into two main types: lawful and unlawful.

  • Lawful Homicide: Lawful homicide refers to instances where the act of causing another person’s death is legal and justified, such as in cases of self-defence or the carrying out a death penalty sentence by lawful authorities.
  • Unlawful Homicide: Unlawful homicide occurs when a person illegally causes the death of another. This category includes various degrees of murder and manslaughter, each with its own set of legal definitions, implications, and penalties.


Murder is a subset of unlawful homicide and is considered one of the most serious criminal offences. It involves the intentional killing of another person with malice aforethought.

Malice aforethought refers to the perpetrator’s intent to cause death or serious bodily harm, demonstrating a reckless disregard for human life.

Degrees of murder

  • First-Degree Murder: This is the most severe form of murder, characterised by premeditation, deliberation, and willful intent to kill. It implies that the perpetrator planned the act.
  • Second-Degree Murder: This involves intentional killing without premeditation or killing that results from an act intended to cause serious bodily harm. It is less severe than first-degree murder but still involves high moral culpability.

Manslaughter: a lesser degree of unlawful homicide

Manslaughter is another form of unlawful homicide, distinguished from murder by the absence of malice aforethought. It is generally considered less morally blameworthy than murder and is categorized into two types:

  • Voluntary Manslaughter occurs when a person kills another in the “heat of passion” without prior intent to kill, usually in response to adequate provocation.
  • Involuntary Manslaughter refers to unintentional killing resulting from reckless or criminally negligent behaviour, such as driving under the influence, leading to a fatal accident.

Legal ramifications of homicide and murder

The legal consequences for murder and other forms of unlawful homicide are severe, typically involving lengthy prison sentences, life imprisonment, or, in some jurisdictions, the death penalty. The specific penalties vary depending on the jurisdiction, the degree of the offence, and any mitigating or aggravating circumstances present.

Homicide vs Murder (Difference between homicide and murder)

What constitutes malice aforethought in a murder case?

It refers to the intentional decision to cause death or grievous bodily harm to another individual. Malice aforethought does not necessarily imply spite or hatred towards the victim but denotes a level of intent or recklessness that exhibits a disregard for human life.

It can be expressed where there is a clear and deliberate intention to kill or implied where there is an intention to cause serious bodily harm, demonstrating a depraved indifference to human life.

The presence of malice aforethought is crucial in a murder case, as it elevates the crime from manslaughter to murder, impacting the severity of the legal consequences and penalties imposed upon conviction. The prosecution is responsible for proving its existence beyond a reasonable doubt in a murder trial.

Can a person be convicted of murder if they didn’t commit the killing but were involved?

A person can indeed be convicted of murder even if they did not physically commit the act of killing but were complicit in the crime. This concept is known as “felony murder,” where an individual participating in a felony can be held responsible for a death during the commission of that crime, regardless of whether they directly caused the death.

For instance, if a person acts as a getaway driver in a bank robbery and someone is killed during the robbery, the driver can also be charged with murder.

Additionally, the law recognises the principle of “joint enterprise” or “accomplice liability,” where individuals involved in planning, aiding, and abetting a crime share responsibility for the consequences, including any resulting deaths. The degree of involvement and the specific circumstances dictate the charges and subsequent penalties.

How does a lawful killing differ from an unlawful killing?

A lawful killing differs significantly from an unlawful killing based on its legality and justification under the law. Lawful killings are permitted by law, typically occurring when an individual is defending themselves or others from imminent harm or when law enforcement officers act within the scope of their duties, such as preventing a serious crime or protecting the public.

Examples include justifiable homicides in self-defence scenarios or the carrying out of a lawful death penalty sentence. Conversely, unlawful killings are prohibited by law, occurring without legal justification or excuse.

These include instances of murder and manslaughter, where individuals intentionally, recklessly, or negligently cause the death of another person.

Conclusion: Homicide vs Murder

While homicide and murder are often conflated, understanding their legal distinctions is crucial. Homicide is a broad term encompassing all acts of one person causing the death of another, whether lawful or unlawful.

Murder, on the other hand, is a specific, intentional, and unlawful form of homicide marked by malice aforethought.
