Do you like Lion King?

I've only seen it twice, so maybe I missed some things.

Was Simba just gonna continue walking the forest for years and years unless Nala found him?

Did He have a destination in the forest or just to keep Tamone and Pumba company?

Is there a backstory on why Scar doesn't like Mufasa? I know he wanted to be king, but is there another reason he hated his brother?
