I suppose....

well as merida said her little brothers get away with murder and they also wont help her til she begs so she isnt that spoiled (but still is spoiled)
jasmine has EVERYTHING and is treated like the rich royal girl she is, i think it shows even more how spoiled she is that she doesnt appreciate anything she has too

I don't really see how Merida is spoiled. Jasmine is spoiled on a material level though, and considering her wealth and status that's expected.

I don't really see why everyone says Merida is spoiled

I don't think Merida is necessarily spoiled. She's often ordered to do things she'd rather not, and she doesn't usually get away with being disobedient, unlike her brothers. I can understand how many think she's a brat, but spoiled is another thing. Her average day seems...planned by her mother, not by her own decisions.

She's a spoiled brat, but I do still like her.

I agree with what everyone's said about Jasmine. She's lived a life of complete luxury, and has everything she could ever want except her freedom. Merida on the other hand hardly gets away with anything. She's just disrespectful.
