But I just don't see all of his friends just chilling there watching him do it. Even if they are supposedly dead, it would just be weird that they are trying to get their friend to die instead of live on and be ok. And if Jin is the only one alive... it would just be freaky to have him calmly film his last living friends suicide. "Like yeah man, you're my last living friend... I think you should die too, I really wanna be alone right now." ;)
