Degrees of murder refer to the classification of homicide based on the intent and circumstances surrounding the act. The primary categories are typically first-degree murder, which involves premeditation and intent to kill, and second-degree murder, which is characterized by intent to kill but without premeditation. Additionally, some jurisdictions recognize manslaughter as a lesser charge, which may involve killing without malice or intent, often in the heat of passion or due to provocation. Understanding these distinctions is crucial for legal proceedings and determining appropriate penalties for offenders.
