The big problem is that humanity have "derailed" so much

If you are farmer and plants billions of apples....You water, nourish and care for the apples continously but they end up producing bad fruits... only very few produce good fruits. What will you do to the billions of apple trees? An experienced farmer will definitely destroy them all except the few good ones. He will use the fruits from the few good ones to "repopulate" the farm with new apples.
GOD is the farmer. He has been so merciful to us despite us not bearing good fruits (good in GOD's standard). HE has been blessing us always and for a long time despite our bad fruits. He is not really like the impatient farmer who destroys impatiently.
Unfortunately evil has grown so much. We have derailed too much and are still blind to our evil.
HE is shaking the earth and warning of what is coming server judgment , but only few are really aware and paying attention.
