I don't think the point of the statement was that the exact purpose of his (or anyone's) life is to be specifically better than anyone else, but rather a broad statement with regards to the fact that if we were all identical (which is to say all as equal skilled, talented, or what have you) there would be little point to the lives that most of us live.
Of course, that's just what I took from it. Feel free to correct me, ZeaLitY.
I tend to lean to Mr. Molecule's position insofar as the redemption of people who have done heinous things is concerned. Mind you, I don't think the issue is so much whether one CAN be redeemed. I would agree with Kyronea that the potential to do so is within everybody. The more important question is WILL they be redeemed. Is the individual in question actually willing to follow a better path? If so, how can anyone else know? It's entirely likely that someone who has done terrible things, when offered a chance at redemption, will tell anyone who will listen just about anything they want to hear.
It comes down to a matter of trust, and since we can only truly gauge the attitude of a person based on their actions, is it possible to trust someone who has committed very serious crimes?
Further, it's very easy to discuss such matters in the comfy confines of an online forum (mmm, mmm...iced tea and a cushy chair), but it becomes a different issue altogether when one is dealing with actual matters. I suppose depending on where we all come from, we have different justice systems to deal with the matter, but in any case I've always been of the mind that there should be more consultation with the wronged parties or, in the case of their murder, their families. The perspective of the people who have been harmed is always paramount in such matters. Now, having said that, I do know that people can be bitter and angry, and I'm NOT saying we should go around slaughtering petty criminals at the behest of the victims.
I suppose it boils down to a simple question. Is it possible to respect the rights of someone who has willfully violated the rights of another? I can honestly admit, I have a hard time doing so.
Also, in the spirit of directing things back (somewhat) to the topic at hand, I have noticed in another thread (I forget which), people discussed the nature of Lavos and the discussion did turn to the issue of redemption for Lavos regarding the activites which make up the game. I think that the game creates so much insight into such matters is a fine reason as for why we enjoy this game. It's an enjoyable experience to have genuine issues raised by so fun a means as a video game.
