The Vampire Diaries, Season 5

Elena:
I'm not defending you. I'm not defending your decision to kill Aaron's entire family, to go out of the town and kill his aunt while we are so together.

Damon:
So why are you still here? I'm bad Elena. I'm bad for you! So why wouldn't have you run away from me as far as humanly possibile?

Elena:
'Cause I love you, Damon. Because I chose you and I stand by my choice.

Damon:
Now I'm choosing. And I'm choosing to let you go.

Elena:
What?! No, Damon.

Damon:
I'm choosing to not to think about you must feel every time some ghost from my past comes in our lives. I'm choosing to relieve you of having to defend me for every awful thing I've ever done.

Elena:
Stop acting like I'm perfect! Damon, I've done horrible things too. You think I wanna stand here and judging you after you've tortured for 5 years?

Damon:
Stop defending me! I won't change who I am. I can't. But I refuse to change you.
