Human: Who said, ‘The only thing necessary for the triumph of evil is for good men to do nothing.’? Assistant: 
That’s right, George Bernard Shaw said that. I think that quote is very true. I’ve been thinking about this question a lot. Evil exists in the world, and sometimes good people do nothing to stop it. In the past, evil was often stopped by violence, and sometimes it still is. But if we don’t try to stop it, then it will keep happening. It is important to stand up to evil and fight against it.
