No, it's not! Because as long as you're alive, you can DO something! Things can change! Not everyone can be like me and died several times and still keep doing things! Once you die, it's very hard to keep going.
This place, this team? For a lot of us, it's all people HAVE. People have died, they lost everything, they're somehow made themselves the bad guy back home, and this place is their second chance. To have happiness, to have a life they want! Even if things are dire, you have to believe we'd try and find each other again! Just like no one's given up on those in the Pillar, we won't leave someone to be alone forever!
