Of course I'm correct. Humans are able to and WILL cause evil in the world, you just can't stop them, so it IS how the world is supposed to work. There is no possibility of everyone being perfectly good. We're not engines, we WILL fail. That doesn't mean we shouldn't avoid it though.

It's exceedingly unlikely that everyone could be perfectly good, but the world would function if they were. 

Evil is not a necessary component. It's not required. There is no excuse for adding it to to the mix. 

Good and evil are not in a 'without evil you can't have good'. The truth is that without good you can't have evil. With evil gone, however unlikely that would be, you could still have good. They're not in a 'ying and yang' balance. That's bullshit thinking to excuse some people who want to feel better about their own personal selfishness or that they're involved in hurting people.
