V

In V for Vendetta, V murders select individuals for ' the greater good' as well as blows up a few buildings (that I'm sure were full of people), to bring about his revolution.  He makes it clear that killing is not a moral problem for him, as  he slashes most men who get in his way.  Evey asks him at one point if he will kill again,  to which he tells her yes without question. The only time he shows a little sympathy  is with the coroner, whom he lethaly injects  as she sleeps and once she wakes he listens to her story.

"Is it meaningless to apologize?"
"Never."

Kagan's essay compares harm for harm's  sake and harm for a greater end result. If you look at V as a character,  he demonstrates both.  Evey discovers that he is killing the doctors from Larkhill for what they did to the women who was in the cell next to him.  Here he is killing to kill, to get back at the doctors and scientists. This motive, however  is not as clear as his want to cleanse the corrupt government of London.  This can  be viewed as  harm for the greater good,  with the hopes that taking down the government who tortures and rules with fear might in the end save more lives.  It may seem that killing so many innocent people is not necessary  yet if you look at any revolution in the past, to make gigantic changes, unfortunately  lots of people end  up dead.
