* He's greedy: He wants the lamp for himself, but his plans often change as he sees new possibilities for power and control.
* He's indecisive: He often hesitates in his decisions, and his plans sometimes fall apart because he doesn't think things through carefully.
* He's manipulative: He manipulates people to get what he wants, but he's not always sure how to go about it.
While not explicitly "wishy-washy," Jafar's lack of focus, constantly changing plans, and manipulative nature could be perceived as such.
It's important to remember that "wishy-washy" is a subjective term, and it's possible that you might interpret another character in Aladdin as having these traits. If you can provide more context about what specifically makes you think a character is "wishy-washy," I can give you a more specific answer.
