Paradise is all we long for, all we want to achieve, whether on earth or in a possible life after death. And our imagination tells us that paradise has to be a place of peace and joy, a place where milk and honey flow by and all kinds of delicious fruit decorate the trees. No one harming the other one.
But to achieve this, every human either good or bad, of which the bad might not have access to this paradise, would have to forget every single grudge it might hold against anyone, and if it forgets this it would not be the same person as before. Let's assume the only way of a peaceful coexistence of a cluster of people would be, that every thought and memory would have to be erased. like it never was there before.
And now you have a bunch of peacefully coexisting people in a superb land with no idea of what they got.
Now this is an area where no one knows anything, and if you found it, you'll be like the other ones, knowing nothing at all.
Would you be happy?
Would you even know how to be happy?
Would you feel free? Find someone to talk with? Be able to talk or even know who you could talk to?
So why is everybody looking forward to this place? Why don't enjoy your life on earth and feel free? Why think it is a clever idea to kill yourself among other people, fighting an unholy war against someone who believes in something different? There is no point in doing that, right?
And if those people come to paradise anyway, maybe even in the same place you might be, what have you achieved?
You could just have let nature take its time, it would anyway end like that. Don't try to accelerate it.
It already happens fast enough.
