You can kill me or not. Either way, I win.

The Mirakuru isn't what made me hate you! The end is near, but maybe I'll be merciful enough to let you live and see your city burn!

Lance: You've killed before. Tonight I suggest you get back in the habit.
Felicity: He's wrong.
Oliver: He's right.

Slade: Goodbye Mr. Blood.
Sebastian: I loved this city!

Moira: There's only one way this night can end and we both know that, don't we, Mr. Wilson?
Oliver: Mom!
Moira: Please tell me both my children will live.
Thea: Mom! What are you doing?! Mom!
Moira: Thea, I love you. Close your eyes baby!
Oliver: NO!
Slade: You possess true courage. I am truly sorry you did not pass that on to your son.

Oliver: Oh you psychopath! Shado...Shado wasn't yours!
Slade: No. She was yours. Until you chose another woman over her!

Slade: Don't worry. I am not here to harm you.
Laurel: Go to hell.
Slade: All in good time, I'm sure. But before then, I've come to Starling City to see Oliver Queen suffer.
Laurel: Oliver? What?Why?
Slade: Because he's not the man you think he is.
Laurel: How would you know that?
Slade: Because I know Oliver Queen is The Arrow.

Your brother has a secret, Thea. Would you like to know what it is?

Oliver: How'd you get off the island?
Slade: That is your first question/
Oliver: Well, you've made it pretty clear that you're not going to tell me where my sister is so, yeah, that is my first question.

Oliver: They're calling you Deathstroke.
Slade: That's a bit flamboyant. I like it.

You cannot die until you have suffered the same way that I have suffered, until you have known complete despair -- and you will. I promise.

Five years ago I made a promise. Do you remember? Well I'm here to fulfill it. See you around kid.

Arrow Quotes

There are people in this world who deal only in extremes. It's naive to think that anything less than extreme measures will stop them.

Amanda

Laurel: Helena, you don't have to do this.
Helena: Yes, I do. Because once you let the darkness inside, it never comes out.
