It really helps to go back and read the first half of the bible to understand from the couple thousand years of history lessons given how things like that work.
As shown in the bible, many times if the good people work hard, root out the evil, destroy the wicked, live righteously and do what is right and refuse to allow for evil in their midst, the promised judgements and bad times are delayed until the faith of man fails and they descend into wickedness and then the promised judgements and hard times come.
There is no specific time listed that certain future events have to take place, only the signs which will clearly show you when you are living it.
Eventually the faith of man will fail and Evil will have it's day in the sun, that part is unchangeable.
But YES, good men had they done what was right instead of worshiping the laws they made and their own creations of government, instead of God and what was right, had they rooted out the evil, refused to compromise with sin, refused to allow the servants of the Illuminated One to manipulate them with lies and deceit and pride and sloth and greed and laziness, we would not be in the world we are in now and the dark times would not seem to be looming so imminently.
If all the good folks were to suddenly wake up at once and dedicate their lives to stopping evil, stopping fighting each other, stopping oppressing each other and taking back the world and destroying evil, YES the judgements could be pushed back. But it's not going to happen because even amongst the "good" not enough folks would be willing to give up everything together and work together to do what must be done.
