These people you mention are good people but not necessarily because religion has made them that way - they would still be good people regardless.
Far from the truth. Most Christians were not good people to begin with, but were transformed by the changing power of Jesus Christ. George Muller was a scum bag, no good for society until he became a Christian. Read this:
Before accepting Jesus Christ as his Lord and Saviour:"A few solemn thoughts and desires to lead a better life came to him, but he continued to plunge deeper and deeper into sin. Lying, stealing, gambling, novel-reading, licentiousness, extravagance, and almost every form of sin was indulged in by him. No one would have imagined that the sinful youth would ever become eminent for his faith in God and for his power in prayer. He robbed his father of certain rents which his father had entrusted him to collect, falsifying the accounts of what he had received and pocketing the balance. His money was spent on sinful pleasures, and once he was reduced to such poverty that, in order to satisfy his hunger, he stole a piece of coarse bread, the allowance of a soldier who was quartered in the house where he was. In 1821 he set off on an excursion to Magdeburg, where he spent six days in "much sin." He then went to Brunswick, and put up at an expensive hotel until his money was exhausted. He then put up at a fine hotel in a neighboring village, intending to defraud the hotel-keeper. But his best clothes were taken in lieu of what he owed. He then walked six miles to another inn, where he was arrested for trying to defraud the landlord. He was imprisoned for this crime when sixteen years of age.
After his imprisonment young Muller returned to his home and received a severe thrashing from his angry father. He remained as sinful in heart as ever, but in order to regain his father's confidence he began to lead a very exemplary life outwardly, until he had the confidence of all around him. His father decided to send him to the classical school at Halle, where the discipline was very strict, but George had no intention of going there. He went to Nordhausen instead, and by using many lies and entreaties persuaded his father to allow him to remain there for two years and six months, till Easter, 1825. Here he studied diligently, was held up as an example to the other students, and became proficient in Latin, French, History, and his own language (German). "But whilst I was outwardly gaining the esteem of my fellow-creatures," says he, "I did not care in the least about God, but lived secretly in much sin, in consequence of which I was taken ill, and for thirteen weeks confined to my room. All this time I had no real sorrow of heart, yet being under certain natural impressions of religion, I read through Klopstock's works, without weariness. I cared nothing about the Word of God."
After accepting Jesus Christ as his Lord and Saviour:"Now my life became very different, though not so, that my sins were all given up at once. My wicked companions were given up; the going to taverns was discontinued; the habitual practice of telling falsehoods was no longer indulged in, but still a few times more I spoke an untruth... I now no longer lived habitually in sin, though I was still often overcome and sometimes even by open sins, though far less frequently than before, and not without sorrow of heart. I read the Scriptures, prayed often, loved the brethren, went to church from right motives and stood on the side of Christ, though laughed at by my fellow students.
Greatest of all Muller's undertakings was the erection and maintenance of the great orphanages at Bristol. He began the undertaking with only two shillings (50 cents) in his pocket; but in answer to prayer and without making his needs known to human beings, he received the means necessary to erect the great buildings and to feed the orphans day by day for sixty years. In all that time the children did not have to go without a meal, and Mr. Muller said that if they ever had to go without a meal he would take it as evidence that the Lord did not will the work to continue. Sometimes the meal time was almost at hand and they did not know where the food would come from, but the Lord always sent it in due time, during the twenty thousand or more days that Mr. Muller had charge of the homes.
