The Lion King is about facing your past and accepting it, no matter what you may have done, in part because forgiveness is always possible.
I’ve always found “Hakuna Matata” to be an interesting choice for a song.
It’s an upbeat number that is clearly designed to be the ear worm tune that it became, and yet, it’s a song whose message flies in the face of that which the movie as a whole is trying to convey.
