关于共犯关系脱离的认定问题,"因果关系切断说"因符合现行以因果共犯论作为共犯处罚根据的理论构架,占据着处理该问题的通说地位。但是该说也暴露出了脱离标准过于严格的问题,因此围绕因果性的切断进行"规范地"软化处理逐渐成为这一领域的有力观点。但是该处理方法也暴露自身标准不明确的缺陷。在这样的背景下,有望采取这样的理论结构,即基于先前行为作为义务理论,认定脱离者脱离前行为对于其他共犯人造成的法益侵害结果不存在作为义务,因此不用绝对实行原先基于因果关系切断说所要求的"避免结果发生方能排除因果性影响"这一条件。这使得在原有理论基础上,对是否避免结果发生进行了更具有理论整合性的处理,而不仅仅只是从因果关系的有无层面进行自然性的考察。
