Captain America Ironman Civil War

Wonder why have a civil war?

Why Ironman and Captain America fought among themselves and because they have a civilwar played Mary Jane Watson died in the war civil, because I saw a picture of the stone grave spiderman embracing MJ

the premise for the CW was innocent ppl were killed in a fight.thus causing ppl and gov. to enact a law calling for heroes and villians to reveal their alter egos to the public. IRONMAN bascially both CAP and had different views on the registration was act.CAP aganst him as IRONMAN was for him.
