Call me sadistic, but I didn't actually feel bad when Muffy was killed.
The first time I
actually watched The Lion King was November of 2012, and at the time, people on the Internet were making memes of his death, praising it for its emotional impact. And, of course, this was a huge spoiler for me, not having seen the movie and all, so when I actually got to watch TLK, I was watching it while being fully aware that Muffy was going to get killed by Scar.
Just like how knowing that Vader was Luke's father really messed up Star Wars 5 for me.
And... I'm just one of those people with overly comical minds... Humour, be it accidental or intentional, takes away from the sad emotional experience of things. The spoiler will tell you more.
When Muffy died, I thought Simba kind of asked for it, since he just couldn't wait to be king. Be careful what you wish for, Simba.
