[Morwen]

I don't equate "dealing out death in judgment" with situations that involve self defense or the defense of others. Bilbo killing Gollum in self defense or a parent killing Gollum for attempting to murder his child is not the same as Frodo sitting in his living room making pronouncements on the fate of someone.

I agree that Gandalf is telling Frodo don't rush to judgment. But as for Gandalf's personal position on "dealing out death in judgment" he refrains from doing so at least twice, in the case of Gollum and Saruman. In the case of Gollum, Legolas reports at the Council of Elrond that Gandalf had told the elves of Mirkwood to hope for a cure. In the case of Saruman, in response to a question by either Merry or Pippin as to what he plans to do with Saruman, he states that he doesn't plan to do anything to him and regrets that much that was good now festers in the tower. Both Gollum and Saruman have done things that one might possibly kill them for but Gandalf does not suggest that such a thing be done and others seem to content to follow his lead.
