The answer is Agression , and violence.
The main difference between the two acts is not in the actions per se, but in Agression, the perpetrator may not really intended to harm others because his/her actions derived from their personal egos in order to appear as capable in order to increase their value. In violence on the other hands, the perpetrators tend to have a big intention to cause harms to their target.
Answer:
In both "The Black Cat" and "The Tell-Tale Heart," the main characters open the narratives by convincing the reader he is not mad. The narrator then proceeds to explain why this is the case, and the story provides justification for his actions. The narrators believe their mental health is critical information for the reader to grasp, causing the reader to wonder if they are really crazy after all. The murder victims of both stories share similar characteristics, for instance, the victims' eye is an important aspect of both. In "The Tell-Tale Heart," the entire purpose of killing the old man was to rid the narrator of his cloudy blue vulture eye. The narrator of "The Black Cat" was also disturbed by eyes as he gouged out his own cat's eye and his new cat possessed an eye deformity. The eye is very significant as it is a key factor that leads the narrator into murder. The murderers also shared very personally, intimate relationships with their victims. The narrator of "The Tell-Tale Heart" repeatedly expressed his love for the old man, and the narrator of "The Black Cat" killed his beloved wife and two favorite pets. It was interesting to discover that the thing the two narrators loved most was their object of affection, yet it became the thing they decided to kill.
Hope this helps, have a nice day/night! :D
