Elena Is Not Cute Anymore at TVD Season 4

I have followed The Vampire Diaries from Season 1 to Season 4. I didn't miss any episode. And if you are like me, you must know that the waiting time is so torturing. And a week we only just watch the latest episode.

If you watch The Vampire Diaries, you must know that Elena is a vampire in season 4. But it seems that she is not good at being a vampire. In the TV series, she is a kind and warm girl. But when the desire of blood is strong, she cannot control herself. She depends on Stefan, she hopes Stefan can help her and guide her how to be a vampire without hurting other people. However, Damon doesn't think she should repress her desire.

In the latest episode, Elena cannot control herself again. She killed the vampire hunter. But she blamed all on Stefan. This makes me very angry. Why does Elena think Stefan should be blamed for for what she did? She is not that strong and she cannot control herself. She killed someone because of her own rage. But she blamed all on Stefan. So I don't think Elena is a cute girl anymore.
