If there was no evil would there be no good and vice versa? We are all raised to know good from bad, kind from hurtful right from wrong... But would these things exist if the worst of the two wasn't there to coinside with the other? I have come to think that yes they would still be there, but without us having one to compare the other against we wouldn't actually know thus kind of cancelling it out. I think if there was no bad there would be no good due to us without the bad not being able to identify the good in something.
