in/un/ is mentioning the language of things that are the opposite of the meaning. like un-realistic, in-tolerable. like the un-existance of the world is in-tolerable or un-bearable but it would be more safe

-in/un/ but safe-

If there were no people, there would be no murder.
If there were no children, there would be no predators.
If there were no sex, there would be no rape.
If there were no animals, there would be no vegetarianism.
If there were no problems, there would be no solutions.
If there were no thoughts, there would be no feelings.
If there were no everything that which is, there would be nothing-

And nothing seems a lot better.
