I'm (re-)watching a lot of old cowboy tv shows and movies from before the '60s. The Civil War is a common thread in these shows. A near universal take on the subject is one of reconciliation - binding up the nation's wounds in Lincoln's words. John Ford's treatments in his westerns and the Judge Priest movies being exemplary instances, and on TV
The Rebel.
These people who have picked this nearly healed wound open into a festering sore are despicable, evil individuals who seek personal aggrandizement at the expense of others' suffering. They are truly hateful.
