The Lion King: To Be Successful, Sometimes People Got to Die
Simba always knew that he was going to succeed his father, Mufasa, as the next Lion King. But fate liked spitting in poor little Simba's face, and his dear old dad got trampled to death by wildebeests. Of course, Mufasa's death was really caused by the evil Scar, Simba's uncle.
Later, all grown up, he reclaims his thrown and Scar suffers the double whammy of falling off a cliff and getting torn apart by hyenas. So after two particularly nasty and horrendous deaths, Simba finally becomes the lion king.
The Supposed Message:
We all have responsibilities we can't ignore. And don't trust that creepy uncle.
The Actual Message:
In order for you to be successful, other people will have to pay. And ultimately, that's okay, because the ends justify the means!
First you have Scar, who knew he couldn't be king of the pridelands until that dick Mufasa and his brat son were out of the way. So Scar did away with both of them, killing Mufasa and banishing Simba, and, as a result, he got to be king for a descent amount of time.
Then when Simba started to grow some balls, he took back his throne... but only after Scar himself took a dirt nap. It's true that Simba didn't intentionally kill him, but you know who did? The screenwriter. After all, the movie doesn't end with Simba convincing Scar to renounce his evil ways, or putting Scar in lion jail.
