As sinners, it is not our place to judge. The Bible tells us we will all one day have to face Him, and only He is worthy of judgement.
But why do you judge your brother? Or why do you show contempt for your brother? For we shall all stand before the judgment seat of Christ. For it is written: "As I live, says the LORD, Every knee shall bow to Me, And every tongue shall confess to God.” So then each of us shall give account of himself to God. Romans 14:10-12
We do not know the truth behind this story and we may never know the truth. I do, however know this truth...
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. John 3:16
This does not say For God so loved the "nice people" or "perfect people" or "sinless people", it clearly says "For God so loved the world"!
So, before you are so quick to judge someone else, instead pray for them and offer forgiveness.
And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses. Mark 11:25
