It should not be done at all.That was the stupidest mistake marvel ever made.If they kill her off it will make Peter look like a selfish jerk going after Gwen for his own selfish desires.
Thats why it was so stupid that they killed her in the comics was after that,he should never have dated mary jane after his love for Gwen was responsible for getting gwen killed and yet,they killed off nice sweet gwendy for that ****,stuck up,air headed,inconsiderate, wild party girl ***** Mary jane.Plain stupid.spidey fans burned their comics after they killed off gwen then.does sony really want to be stupid and antagonize the fans AGAIN?

Peter will be a jerk if they kill Gwen because of his promise he broke to Captain Stacy to stay awy from her.He will be a jerk if they kill her off because his own selfish desires will be responsible for her dying.
