"the car infront of him stopped at the green light and inspite of breaking hard my husband hit him from behind."

 But it was your husbands fault, he was either driving too fast, too close , not paying attention or a combination of these. If you rear end someone it is always your fault because of the 3 factors i mentioned above.

And you dont stop for red alone, you stop for amber and get ready to stop for flashing green.  

"Deaths in the Bible. God - 2,270,365
not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
