world peace

So I was out of ideas, and I told the girl to tell me what is on her mind, and she talked about world peace. She talked about why there is not any world peace. She said "in a peaceful world everybody would get what they want to have peace but what about the crazy people in the world who get peace out of killing people or molesting children ? there peace would interfere with the people who are normal who don't like that." Rhea. SHe talked a little bit longer, but I started zoning out. Anyways I like what she said about how some people see peace in different ways.
