Praising Someone for Noble Actions, Blaming Someone for Ignoble Actions?

Question

In a speech, would you rather praise a historic figure or a literary character for their noble actions? or blame them for his or her vices? Who? Why?

Answer 1

That would depend on the person, for instance

Martin Luther King would be a person I would praise for his actions in fighting for equality,   and

Adolph Hitler would be hard to praise, and deservedly would be scorned, and blamed for the events of the 1930s, and 1940s.
