I'm taking a philosophy class right now and, in its discussion of evil, the author of our textbook assumes that natural disasters are evil. It's under the discussion of 'the problem of evil,' which is basically, if there is an all-good, all-powerful God, why is there evil? He of course discusses free will -- if God took away the choice of evil, humans would be robots. But he says that does not explain why there are "natural evils" like tornadoes and hurricanes.
My question to you: Is that an appropriate use of the word 'evil'?
