Christians , explain to me why your god created evil...

According to isaiah 45:7 .. This verse states clearly evil/woe/disaster/destruction.. Depending on what version of bible you use..

Why did he create evil ?

I don't know why you ask this question specifically to christians. I'm not a follower of any religions or spirituality. In any religions (with a god), this god would need to either to have created evil himself or at the very least allow evil. I think most religions goes with the idea of a perfect god having allowed evil (aka allowing free will). For atheist/agnostic, evil is not a problem (obviously) since it's only part of nature like a tiger eating another animal (or for goodness: humans helping each others to grow crops thus promoting their collective survival and quality of life), what is defined as evil is subjective and part of our various human cultures.

Another question would be why god allow diseases, natural disasters with a lot of death, still born baby, etc. Each religions also have their own answers which usually involve supernatural forces and retributions.
