They've all had there troubles really. I mean we don't know much about Regina's past yet but losing her lover had to be tough. And then with Snow, people have attempted to kill her numerous times, she had to give up Emma and then found her husband practically dead after doing so.

Though in the long run I'd probably consider Emma's to have been more difficult out of what we've seen so far because it seems like her's has been the longest.

I mean she grew up thinking her parents abandoned her, never had a stable home, from the looks of it had no close friends, I mean the girl was going to spend her birthday alone in her apartment with a cupcake she bought her self. And that's not even including the stuff that happened in Storybrooke.

I think they've all had there own struggles and personal demons to battle. I think it's wrong to say one's troubles is worse than the other. Because to each of us our "troubles" seem like the biggest battle, however small they may actually be they always seem more difficult and larger than they are.

I actually don't feel sorry for Regina/The Evil Queen at all

I feel the most sympathy for her.

I believe she brought it all upon herself. She could've have started a new live and could've been happy. Instead she kills her father who did nothing but helped her. I just want to strangle her! She's horrible! So in other words I love her!

In a way she bought it on herself but, Snow was the one who caused this landslide when she shared that secret. Lol I love her as well. x3

^I think it's been vaguely hinted that when Snow shared that secret she was actually very young... (and there's also the fact that (SPOILER-ISH) : they cast a 12 year old girl to play Young Snow White in an upcoming episode XD) Not sure for which episode but I'd assume it's for the one where we learned what happened between them.

I hope we get to find out soon!

By far, have you seen her mother! That's all I have to say.

All their lives are difficult, I can't choose.

They all have hard lives and some of them chose a wrong path.
