I would not want to speculate on any specific disaster because, first of all, it may be taken as these people deserving it. Also, I am not God, nor pretend to be God. Only God knows.
In general, all suffering is because of original sin. God did not intend us to live like this. And sin does cry out for the justice of God in this life and/or the next.
Gay and Lesbian Decadence Feast was suppose to happen over Labor Day weekend. I think it is cancelled, of course. I don’t believe this was responsible because there are things like this going on all the time. Why there? Why now?
The good and bad suffer because of the individual sins of men, the collective sins of men and because of original sin. We are all together on the same boat, so to say. Thousands of people died in the San Francisco earthquake of 1905, thousands died when the Mississippi flooded in the 1920s, thousands, thousands, thousands. The way the state of the world is: weather, geology, etc - bad things are bound to happen. What God has to do with each incident? Snowstorms, flooding, tornadoes, hurricanes, etc?
Jesus said we are to carry our crosses and suffer with him. How we respond to our own crosses not only effects our lives but the lives of those around us. Do we respond with love or hate?
We must try to elevate suffering as much as we can in this age and when Christ returns our great hope and promise is there will be no more suffering.
