When Caroline says "I did once when I thought he was worth it " in this gifset below who is she talking about?? Klaus? Damon?

Definitely about Klaus. Not Damon.

If you think about s4, or in general the dynamics between Klaus and Caroline, she definitely saw the good in him despite his actions, and she definitely felt his charm.

But then he killed Tyler’s mom and she was mad about it. That’s why in 4×17 she tells him she thought he was once worth it (of seeing the good despite the bad actions) but after he crossed a line so she changed her mind.

She also adds “People who do terrible things are just terrible people.”
