Pardon?This part is in the future... so doesn't matter...
WTF are we talking about if not the future?
WTF do you think omniscience means?
Knowing everything, including the future: this means that, (as per the f*cking OP), god knows before we do what we are going to "choose". therefore we don't actually have a choice.
What the hell have you been talking about up to now?
No it shouldn't.So your question should be... If I travel to the future and know what happens.. should I bother going back to the beginning again?
We are talking about what the existence of knowledge of the future does.
