The life of a man is in the Hands of the lord, he descides who leaves and who dies because he created every single thing in this world, he knows the beginning and he knows the end.
So coming to say the bad dies and the good lives it's a little bit not true because we all are all created in the image of God and his likeness, most often you will see that the bad leaves longer than the good it's not because God is partial but because of his mercy endures forever.
So when ever it's God's time a person goes and when God says it's not yet time then it's not happening.
