The better reason for recognizing the defense of abandonment is that it is conceptually connected to the attempt itself. The effort to desist and to check the consequences of the attempt shows that the "criminal intent was not as firm as would have been required for the execution of the offense." 50 Though this rationale makes sense, it does not adequately explain the nuanced decisions of the courts. In particular, it does not explain why American thinking tends to demand a total renunciation of the criminal purpose 51 while German law is content with a standard that stresses whether the attempter is the "master of his decision." 52 In the end, unfortunately, we must conclude that the factors influencing the contours of abandonment represent a mixture of conceptual and political considerations.
