“I did not do it, because I would not do it”

When hard proof is absent, someone who faces an accusation can seek assistance in arguments making it plausible that (s)he ‘did not do it’. This paper deals with an argument saying that the accused would never do the alleged act because of the harmful consequences it would yield. An analysis and evaluation of this kind of argumentative strategy is demonstrated with examples of two professional cyclists defending themselves against doping accusations.
