Final answer:
The quote exemplifying dismemberment of a corpse is a form of direct characterization, where the character explicitly describes their actions, hinting at underlying character traits.
Step-by-step explanation:
The quote "first of all i dismembered the corpse. i cut off the head and the arms and the legs." is an example of direct characterization. Direct characterization occurs when the author explicitly describes a character's traits, either through a narrating voice or through a character's own admission. The quote is provided by the character, thus it directly describes their actions and in turn reveals character traits, such as being methodical and detached, or possibly exhibiting a cold disposition towards the gruesome task.
In contrast, indirect characterization would involve showing traits through a character's behaviors, actions, dialogue, and interaction with others without directly stating them. This would require readers to infer the traits from the provided evidence.
