The other 2 are better role models IMO.

Just by comparison

She's not a bad role model, but she's not good either

Not a huge role model, really (but I'm not saying she's a bad one).

Maybe because she just really young to be a big role model.

While ultimately she isn't a bad role model nor demonstrates the kind of behaviour that would be appaling, disturbing or deliberately hurtful (although no princess technically does hence why I believe they are all good role models to look up to in one way or another), her delusions and inability to think rationally nearly cost her life, also as princecatcher93 mentioned, her young age prevented her from having any kind of a defining characteristic that would turn her into a particulary good example.

She took an apple from a stranger and believed that if she ate it, her wishes will come true. But again, she's only 14. Still, she isn't a very good rolemodel.

I actually think that she is a bad role model because she is too good. Nobody in real life can be THAT innocent, and innocence isn't exactly a characteristic you can learn.

I already explained in a previous pick. She's quite strong in a way, but in the same time she's really weak in other ways.

Just in comparison...
