The list really goes on and on..
Did she get jealous and petty sometimes? Yes. Did this often lead to her hurting and/or killing people? Sure. But she did it all with such pizzazz, humour and glamour that we always forgave her.
John was a bit of a cad, and if he had been played by anyone but David Anders we might have hated him. That being said, we can't help but love John for the way he sacrificed himself to save Elena.
Nadia's dedication to her mother Katherine, even before they ever met, was kind of sweet. But it was super rude of her to do the spell that made Katherine a Passenger in Elena's body. That's why we weren't exactly heartbroken when Tyler bit her.
Elijah is one of the most powerful vampires on the planet, but you'd never know it from how he acts. Elijah's nonchalance is a thing of true beauty. Whether he's ripping someone's heart out or sipping on some wine, Elijah is always calm, cool and collected.
From when he embarrassed Caroline and Elena in their first class to when he forcibly turned Jesse into a vampire to when he experimented on Damon with the Ripper serum, Wes was a Grade-A D.B.
Being dumped also makes people do dumb things. But while these reasons might be slightly understandable, they still add up to Qetsiyah doing some seriously huge - and world-changing - dumb things for incredibly self-involved reasons.
First, he turned his children into vampires. Then, he made it his life mission to kill his children. Whatever happened to blood is thicker than water?!
So while we're forever indebted to Silas for setting off the tragic chain of events that have made for great, dramatic television, he was a major snoozefest. Still badass though.
When Klaus showed up, he was the first villain who felt truly terrifying. He was more powerful than anyone the gang had faced, and it made the show exciting in a way it hadn't been before. It didn't hurt that Klaus was also devastatingly handsome and ridiculously charming. And once Klaus starting falling in love with Caroline and showing his sweeter side, we felt better about our own crush on him too.
Kol was the lovable misfit of the Mikaelson family. Not nearly as smart of intimidating as his brothers and sisters, Kol was unpredictable and would do anything to save his own skin.
Julian killed Valerie and Stefan's unborn child. Unforgiveable! Julian killed an entire coastline of people on Christmas. Unforgiveable! Julian challenged Enzo to a duel when his life was linked to Lily's. Unforgiveable! The list really goes on and on.
As the charismatic villain of Season 6, Kai was damn near flawless. His hair was probably not insured for any money, but it should have been. He was banished to a prison world for attempting to kill his siblings to become the leader of the Gemini coven.
Katherine is completely and utterly evil, yes, but you've got to respect her for her never-ending dedication to protecting her own neck. Plus, she did it with such flair!
