This premise seems more doubtful. In fact I am sure that a lot of you will want to raise objections to it. Maybe it is perfectly consistent for an all-loving God to allow evil to exist in the world. We will elaborate this point in a bit. Some people deny this.
Nothing is really evil.
In a certain frame of mind, evil might seem powerless and inconsequential. It is difficult for most people to take this view seriously. People are regularly killed by tornados, earthquakes, hurricanes, and other natural disasters. Those events are awful evils. It sounds extremely implausible, to most people, to say that their obvious hatefulness or badness is illusory.
