(3) obligations arising from previous acts;
(4) Obligations arising from legal acts. Adding "self-destruction crime" is actually to further clarify the legal scope of people who have the ability to act in the face of other people's death from legislation. Of course, this range should be strict. While encouraging people to save lives and punishing those who don't save maliciously, it should not be over-expanded, so as not to hurt the innocent. Once people who have the capacity to act within a certain range have the obligation to face the death of others in legislation, it will be logical to move from destruction to crime, which will further improve the existing laws and supplement socialist morality.
