And it's impossible, I suppose, that the intervening injustices or perceived injustices would have changed their point of view, made them thirst for revenge, made them angry? It's impossible that sometimes bad guys DO act as, well, stock bad guys? I guess acting as a "complex human being" means acting as a GOOD human being, but acting the way you've always acted (i.e., as a bad guy) can't be part of being a "complex human being"?
To you, seeing murderers act with mercy seems right and like a true portrayal. Seeing murderers act as thugs seems unbelievable and a clear political hack job.
What about the Count of Monte Cristo? I suppose that Dumas is really showing a lack of subtlety in having a character who started out cool and normal end up a schemer bent only on murder and revenge?
Unfortunately, I forgot the most glaring lesson of arguing with my friend: when somebody is determined to take offense at perceived political slights in a film, there is no point arguing with him. Mea culpa.
