I took a really really good course once titled "the problem of evil" that focused on this question in great depth.

There have been many many attempts to work out the issue you present and frankly every "solution" has some aspect of it that someone doesn't like.

This is historically one of the toughests questions in christian theology . . . and frankly, will continue to be something that theologians beat their heads against for some time.
