I've got to agree with this guy. At the least he should of remained as one of Orochimaru's henchmen till the end of Part 1/The Sasuke Retrieval Arc.He was as useful as most non-main characters were at that point. He was introduced as a powerful, mysterious guy, brimming with potential, and yet, the fate he received from Kishi was extremely illogical. Dosu, the guy who was by far the most intelligent member of his team, decided to directly approach Gaara, despite having backed down to someone like CSM Sasuke. His death didn't even make sense, his character was without a doubt worthy of something other than such a ridiculous end.
