If swearing is a sin (which from what I've read, it is a sin) and you swear before you die and don't have a chance to ask for forgiveness

Do you think God would still send you to hell for it? Even if you swore due to the injury or situation that caused you to die and therefore didn't get a chance to ask for forgiveness. Wouldn't that suck? Live a good life and try and follow what the bible tells you, and than you experience something horrific, yell "Oh Shit" right before you die. Then when you get to the pearly gates God tells you, well since you said that right before you died you can not get in and now you will burn for all eternity.
