Rambling thoughts on the point of LOST, and why nothing else needs to be for certain, because everyone in Life is looking for different answers...

I think that to the characters of LOST, through out the whole series what became most important to them was everyone trying to leave The Island together. This was such an emotionally intense time for everyone, that nothing they would ever do in their lives would feel so important and so necessary. When they died, whether it be on The Island or later in their lives as survivors, they were left unfullfilled. The one thing all of them lived and died with was the regret of losing those people, and that place unfinished. When each one of them died they could not move on, because they were still waiting for everyone to feel safe again. Always holding onto the regret of not doing the RIGHT thing to get everyone HOME safely, and how their own decisions subsquently became life and death situations for each others lives, not just their own. The time of their lives on The Island as survivors, was them constantly looking death (or life) straight in the eye trying to survive. This made them constantly reflect on theirselves, their worth, and their meaning to the world (or island) and to each other. What they all had in common in the beginning was doubt. Doubt of themselves and doubt of OTHERS. This made them self reflect to believe in themselves. Some needed to believe in OTHERS to be led to believe in themselves. In the end what they had in common was FAITH in themselves as OTHERS, and belief in the deeper meanings and connections of life.They connected peices of their stories with each other, as nothing you do in life can be done entirely alone. By forever holding onto that regret and that hope, they were not able to move on until they found each other safe again, the right way, with no regrets. Their redemption was redeeming each other, in the beginning and in the end.
