Montresor in the Amontillado

Montresor is just plain evil.  Yes there are those who would argue that he had some other motive, but the bottom line is that Montresor is evil.  If he really had a beef with Fortunato he should have just talked out his problem and settled it according to the law.  There was no reason for him to go out and commit a cold-blooded murder.  They could have sat down and solved their problems over a cup of wine - perhaps even Amontillado and then nobody would have been dead and he wouldn't be sitting there fifty years later remembering the most horrible event in his life.
