A brief synopsis: one atheist argument is that since God created everything, He is responsible for the creation of evil.However, "evil" is a word that we use to describe certain things that happen to us (most of which are caused by other people).
In reality, it is not a physically created thing at all and, therefore, does not fall within the realm of something created by God. So, the argument is fundamentally flawed. Evil is allowed by God so that free will beings can choose between good (i.e., God) or evil (absence of God).
Without evil, it is not possible to choose between good and evil, and the universe would have no ultimate purpose.
Thanks, Ed!
