I cant really decide. Mufassa was to trustfully, which had lead to his death, and simba is overprotective and draws to fast conclusions... so it's really difficult to say one is better then the other
Tough question...I'd have to say that I was more proud of Mufasa. He inherited the Kingdom at a very bad time. He restored the Pridelands to its power.

Did you ever feel quilty giving Mufasa such a hard task as restoring the Pridelands?
