Such amazing writing. Snape's fury for Lily's sacrifice, whilst simultaneously admitting that he himself has killed. Two powerful men admitting to their greatest faults. This makes me tear up every time I read it!
"Do not pity the dead, Harry, pity those who live without love. This is a fate worse than death. Living without love is worse than living without your soul. You are fully sane and love evades you." -Albus Dumbledore tells Harry in the afterlife, HPatDH
