Title: Question about double spends/transactions listed on blockchain

If you click on the receiving address, it just keeps going on and on forever, each transaction sending to 2 different addresses, 1 where the majority of the money gets passed on, and second a small fraction of the sum, with a couple of the secondary transactions being quite large in the thousands.

Each transaction shaves off a bit, following the smaller addresses mostly lead to dead ends, while others lead to similar loops.

I understand the transaction is listed as a double spend, but I'm assuming that one transaction went through, so what exactly am I looking at?

Is this possibly a malicious attempt at double spending money, attempt to wash the money and make it hard to trace, or just normal transactions going on with a business like gox or satoshidice?

That transaction had inputs that were also used in another transaction, so that's why there is the warning about the double spend attempt.    The transaction you linked has confirmations. It is valid, and is not the double spend.

As far as the double spend transactions that existed at one time ... blockchain.info doesn't retain those indefinitely so there's no telling today what had happened back then.
