Some Ans. Questions 2014 by -'Abdu'l-Bahá- 1 Para

To summarize, one thing may be evil in relation to another but not evil within the limits of its own being. It follows therefore that there is no evil in existence: Whatsoever God has created, He has created good. Evil consists merely in non-existence. For example, death is the absence of life: When man is no longer sustained by the power of life, he dies. Darkness is the absence of light: When light is no more, darkness reigns. Light is a positively existing thing, but darkness has no positive existence; it is merely its absence. Likewise, wealth is a positively existing thing but poverty is merely its absence (74:6)
