This is mainly because the purpose and task of criminal law is to protect legal interests, and the essence of infringing legal interests is to infringe or endanger legal interests; An act that does not infringe on legal interests or cause danger, even if it violates the social ethical order, lacks social equivalence, or violates certain rules of conduct, cannot be the object of criminal punishment. We should objectively investigate the illegality. Subjective factors are not the judgment data of illegality in principle. Intention and negligence are not the constituent elements of illegality, but the constituent elements of responsibility. The object of illegal evaluation is the objective facts ascertained afterwards. Not the behavior itself.
