Ok. The actual quote: "We were instructed not to interfere in any human conflicts unless Deviants were involved," the words were not 100% accurate, but the joke still stands as with most "jokes" they are not usually based 100% on accuracy. Something obviously lost on you.
Also the only thing useless here is trying to waste my energy explaining it to you, as it appears you have made up your mind. You are entitled to your opinion, but it doesn't mean the rest of us have to agree with you. We are entitled to ours as well.
