To properly answer this question, one need to delve into the scripture. The Bible at Revelation 12:12 says: ..Woe for the earth and for the sea, because the Devil has come down to you, having great anger, knowing that he has a short period of time. Because the devil is the one controlling the affairs of the world (1John5:19), that is why humans have been suffering and its going to continue until God take the rulership from Satan and restore the earth back to paradise He purposed it to be from the beginning. Satan is making use of The government and bad people on earth to inflict suffering on human being apart from the fact that anything can happen due to time and unforeseen events like natural disasters
