A person's life is worth 500 credits. Not that a bounty is normally that much because it ranges depending on the planet and other factors, but to make a new life costs 500 credits. It may be the cost of a hyper-space flight I don't know, and it isn't important why it's that much.... maybe it relates somehow to what they are worth.
The planet of Tattooine is desert, but the Sand People have wicker baskets, how? They didn't buy them, could they grow them if they didn't use the evaporators? So how the hell can they have Banthas, they would eat the same amount as an elephant, wouldn't they? Illogical therefore unforgettable.
Also, that apathy is death, worse than death, and "it behooves you to strike down one that you are familiar with for no other reason than to prove that you are superior" I think that's right, he might have said young one somewhere in that.
