Final answer:
Using violence to attain power typically results in more violence and a continuous cycle of aggression. Historical patterns and psychological research support the idea that violence is not a stable means to achieve power but instead leads to further conflict.
Step-by-step explanation:
The play suggests that when one uses violence to attain power, it begets more violence. This means that using violence as a means to gain power will only lead to more violent actions and conflicts.
A good example of this can be seen in Shakespeare's play Macbeth. Macbeth uses violence to become king, but his violent actions ultimately lead to his downfall and the destruction of his kingdom.
