Final answer:
The Godwinian idea about 3. revenge is that it is a mistake and should not be pursued unless it results in social good. Seeking revenge can have negative consequences and perpetuate a cycle of evil.
Step-by-step explanation:
The Godwinian idea regarding revenge is that revenge is a mistake and should not be pursued. According to this perspective, any action motivated by revenge that does not result in social good is considered to fall into the realm of error. The central theme is not whether revenge is justified or a personal choice, but rather its impact on society and the greater good. The excerpts suggest that the seeking of revenge, especially when driven by resentment or personal gain, can lead to negative consequences and further evil.
Moreover, the understanding is that evil might not always lead to a good result and the vindictive cycle can become uncontrollable. Therefore, Godwinian thinking would argue that as revenge often does not lead to any constructive outcome, it should be avoided.
