My crime was trivial? [There is murder in his eyes now. They're small and black and shiny and if he could reach through the screen and throttle Severus, he would.] My crime was trivial. My crime was trivial. James and Lily Potter were not trivial, nor was the crime of their betrayal and murder trivial acts. And to think, she used to defend you.

[He shakes his head and clucks his tongue.] Poor Severus. Someone, please feel bad for me! Look at me, I'm suffering! Yet you accuse me of playing martyr, Well, I'm not. James and Lily are martyrs. The rest of the Order that died, they are the martyrs. Every good witch and wizard you and your kind killed, they are the martyrs. I'm just a dumb chap in a Barge looking to turn a few things around. And I'll be here as long as it takes for me to do that. Years and years and years if that's what's required. I've got time to burn.
