Forgiven for what? Their own personal struggles, or their own jihads? There is nothing to forgive there, because AFAIK, the Quran tells you to wage jihad on certain internal things (DISCLAIMER: I totally do not claim to know everything about Islam, so please, please, if you know more, step in. Royal!! I need you
) I think you can equate their personal jihad as being an internal debate between desire and righteousness.
Now, the "jihad" that the extremists are waging against the US, well... you can make an argument that there is no need to be "forgiven" since they wholeheartedly believe that Allah backs them up in their fight.
