<Snipped quote by Etcetera>
I think you fail to realize how big this actually is. Eventually, you'll be dragged in whether you want it or not. If you want to think about it negatively, you either die alongside your friends trying your best to save existence, or you buy some time, only to be eventually slaughtered as you say, regardless. Or, if you want to think about it positively, you'll save existence alongside your friends as you have before, allowing yourself an opportunity of peace once again.
You're talking emotions right now. I need you to convince me what I can do to make a real difference. The illusions of grandeur or hero work aren't going to be enough for a fight completely out of my league.
