It didn't "go" to anything. Jiraiya is a folklore character and also a major character in the original series if you're attempting to differentiate Shippuden from it. A good writer is a good reader. The consideration for what "good writing" is isn't merely limited to what you find tactical in a shonen manga, or a "character's development" as laity so often posture. What you claim happened to Kishimoto is a merely a phantasm of your own making. It takes plenty of effort to read literature and dilligently study your own cultural heritage.
