My answer: Deeds are good and bad. People are people.
EDIT: Also there are normal people and psychopaths, especially socialized psychopaths. They confuse the issue. I would hate to use the "bad" to described them, I would just use the word psychopath. People who value power over love and have no sense of shame over wronging others.
INFJ husband's answer: People become bad people only when they deliberately do something bad.
