I think context is important here. What is the software you are building? Is it highly critical or possibly life threatening, like a stock exchange trading system or a aeroplane control system? Should the developers be given autonomy to speed delivery? Or should more controls be put in place to ensure delivery of the quality, validated product while possibly slowing down the delivery speed.
"Now it came about after these things, that God tested Abraham, and said to him, Abraham!' And he said, 'Here I am.' And He said, 'Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah; and offer him there as a burnt offering on one of the mountains of which I will tell you.'"(Gen. 22:1-2).
Remember that religious texts are mostly proverbs. These events most probably didn't actually happen, they are trying to communicate moral attitudes via stories... a little like Winnie the Pooh and Friends.
1) does that excuse muhammad's massacres in any way ? Or should I answer with pointing out that atheists are responsible for the biggest massacres of the 20th century perhaps (ie. the communist "opium for the people" folks)
2) you're mostly showing ignorance, as "mostly proverbs" does not apply at all to islamic texts. Random example :
Different religions are different (surprising how controversial such an obvious truth can be).
3) Given that you're comparing moral parables ("lies to convey a greater truth" I've heard it defined, like fairy tales) to actual events, your point is reversed.
