I would argue that evil is inevitably caused by sin. Think about it; the only reason God would create a cyclone (hurricane for U.S.) would be to harm and/or teach those who have rebelled against him. If man did not sin, there would be no need for cyclones. All disasters or similar evil things are in order to either punish us for something in order to shape us to become better (as any good parent does) or just to shape us to become better. If there was no sin, there would be no evil. Simple as that.
That's quite the summary on
WHY God created cyclones!
Job 38:21
Knowest thou it, because thou wast then born? or because the number of thy days is great?
Romans 11:34
For
who hath known the mind of the Lord? or who hath been his counsellor?
Job 36:22-33
Behold, God exalteth by his power: who teacheth like him?
Who hath enjoined him his way? or who can say, Thou hast wrought iniquity? Remember that thou magnify his work, which men behold. Every man may see it; man may behold it afar off.
Behold, God is great, and we know him not, neither can the number of his years be searched out. For he maketh small the drops of water: they pour down rain according to the vapour thereof: Which the clouds do drop and distil upon man abundantly.
Also can any understand the spreadings of the clouds, or the noise of his tabernacle? Behold, he spreadeth his light upon it, and covereth the bottom of the sea. For by them judgeth he the people; he giveth meat in abundance. With clouds he covereth the light; and commandeth it not to shine by the cloud that cometh betwixt. The noise thereof sheweth concerning it, the cattle also concerning the vapour.
Job 38:5
Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
Job 39:1-2
Knowest thou the time when the wild goats of the rock bring forth? or canst thou mark when the hinds do calve? Canst thou number the months that they fulfil? or knowest thou the time when they bring forth?
Job 42:3
Who is he that hideth counsel without knowledge? therefore have I uttered that I understood not; things too wonderful for me, which I knew not.
