Section 8 of the Evidence Act 1950 provides that evidence of motive, preparation, and previous or subsequent conduct is relevant in legal proceedings. Motive refers to the reason for doing something, while intention refers to consciously shaping conduct to cause a certain event. Evidence of motive is admissible but absence of motive does not prove innocence. Motive cannot be proven through hearsay evidence. Evidence of other crimes can also be relevant to show motive. The document discusses these principles and provides examples of how Malaysian courts have interpreted and applied Section 8 in past cases.
