Answer:
The word choice in this excerpt from "The Black Cat" by Poe, particularly his use of "seduced," suggests that the tone exhibited in this passage is "guilt-ridden."
The protagonist seems to be acknowledging his own wrongdoing and recognizing that the "hideous beast" he refers to is the one who led him down this path. The use of the word "seduced" implies that the protagonist was somehow tricked or tempted into committing murder, which adds to the sense of guilt and regret conveyed in the passage. Additionally, the use of the word "consigned" implies that the protagonist feels powerless and trapped, further emphasizing the guilt and remorse he feels.
