结果加重犯作为一种特殊的结果犯，我国刑法总则并未对其作出专门规定，刑法分则条文的表述也很粗疏，从“致”、“造成”等文字中，根本无从窥见结果加重犯因果关系的具体内容。立法的简陋，直接造成司法的混乱，对因果关系的掌握松紧不同，“同案不同判”问题严峻。关于结果加重犯因果关系的理论，主要有一般论和特殊论两大阵营。一般论阵营包括条说说、相当因果关系说、客观归责理论和危险现实化说，特殊论阵营包括直接关联性理论和修正的直接关联性理论。其中，直接关联性理论强调基本犯罪行为的特殊危险直接现实化为加重结果，能够最大程度地限制结果加重犯的范围，但其本身还包括实行行为的内容，故在我国面临体系尴尬。直接实现型的危险现实化说是指，实行行为形成了结果发生的原因，对结果发生起决定作用，进而可以说实行行为的客观危险毫无障碍地现实化为结果。鉴于直接关联性理论和直接实现型的危险现实化说在判断重点、判断方法等方面具有共通的理解，且危险现实化说不会面临体系尴尬，因此，受这两种理论启发，笔者提倡直接的危险现实化说。这一学说以介入因素为切入点，分“介入因素显著轻微”和“介入因素必然发生”两个步骤进行检验。如果介入因素显著轻微，可径直肯定直接的危险现实化；如果介入因素作用较大，必须检讨介入因素与基本犯罪行为之间的关联程度，只有在评定为必然发生的场合，才能肯定直接的危险现实化。“介入因素显著轻微”主要通过“由果推因”的方法，如果得出死因和死期产生于基本犯罪行为，就能肯定因果关系。“介入因素必然发生”必须进行规范化判断。当介入的是主体行为时，主要适用心理法则：一是当介入被害人行为时，基本犯罪行为压制了被害人的自由意志，迫使其不得不以危险方式行为；二是当介入第三人行为时，符合正常的职业营救、紧急避险条件或系挽救密切关系人重大利益；三是当介入行为人其他行为时，前后作为可作一体化判断，两者之间有直接联系，或者事后的不作为不具有期待可能性，未超出基本犯罪行为的不法和有责要件。当介入的是自然灾害、动物侵袭等特殊情况时，主要适用环境法则：如果自然灾害、动物侵袭等具有高度的、类型化风险时，视作必然发生，并将这些风险作为基本犯罪行为的特殊危险内容，当环境恶劣的整体风险实现为加重结果时，也应肯定基本犯罪行为与加重结果之间直接的危险现实化关系。

Aggravated consequential offense is a special consequential offense. The general provisions of China's criminal law have not made special provisions on it, and the expression of the specific provisions of the criminal law is also very careless. From the words of "causing", "causing" and so on, there is no way to see the specific content of the causality of consequential aggravated crime. The rudimentary legislation directly leads to the confusion of justice, the loose grasp of causality is different, and the problem of "different judgments in similar cases" is serious.There are two camps on the theory of causality of Consequential Aggravated Crime: general theory and special theory. The general theory camp includes article theory, equivalent causality theory, objective imputation theory and danger reality theory, and the special theory camp includes direct relevance theory and modified direct relevance theory. Among them, the direct relevance theory emphasizes that the special risk of basic criminal behavior is directly realized as aggravating result, which can limit the scope of consequential aggravated crime to the greatest extent, but it also includes the content of implementation behavior, so it is facing systematic embarrassment in our country. The theory of direct realization of danger reality refers to that the implementation behavior forms the cause of the result and plays a decisive role in the result. Then it can be said that the objective danger of the implementation behavior can be realized into the result without obstacles. In view of the common understanding between the theory of direct relevance and the theory of direct realization of danger realism in terms of judgment focus and judgment methods, and the theory of danger realism will not face system embarrassment, therefore, inspired by these two theories, the author advocates the theory of direct danger realism. This theory takes intervention factors as the starting point, and is tested in two steps: "intervention factors are significant and slight" and "intervention factors must occur". If the intervention factor is significantly slight, the direct danger can be directly confirmed; If the intervention factors play a great role, we must review the correlation between the intervention factors and the basic criminal behavior. Only when it reaches the inevitable degree, can we affirm the direct danger reality."Significant and slight intervention factors" mainly through the method of "deducting the cause from the result". If it is concluded that the cause and duration of death are caused by the basic criminal behavior, the causality can be confirmed. "Intervention factors are bound to occur" must be standardized judgment. When intervening in the subject's behavior, the psychological rules are mainly applicable: first, when intervening in the victim's behavior, the basic criminal behavior suppresses the victim's free will and forces him to act in a dangerous way; Second, when intervening in the behavior of a third party, it meets the normal conditions for professional rescue and emergency avoidance, or it is to save the major interests of the person closely related to the rescue; When there is a direct connection between the two, the possibility of not acting or not acting beyond the expectation of the crime, and the possibility of not acting after the fact. When involved in special situations such as natural disasters and animal attacks, environmental laws are mainly applicable: if natural disasters and animal attacks have high and typed risks, they are regarded as inevitable, and these risks are regarded as the special risk content of basic criminal acts. When the overall risk of bad environment is realized as aggravating results, the direct risk reality relationship between basic criminal acts and aggravating results should also be affirmed.
