It is all Coras fault! As আপনি all said, snow was just an innocent little girl that wanted Regina to be happy but got manipulated দ্বারা that WITCH!!!

Regina should blame Cora! NOT Snow! As Lana ব্যক্ত Regina was thinking: " আপনি little, selfish BRAT! আপনি just wanted me to be your stepmother! আপনি don't care about ME being happy!" Thats what Lana ব্যক্ত Regina was thinking at the time when she was getting dressed for the wedding. But we don't know why Regina went 'Extreme Power-Mad' yet....she went WAY extreme to rid Snow! But...she didn't know any different....

Someday in season 2/3 I want to see Regina confront Cora and apologise to
Snow somehow and get 'redeemed.'
