Case analysis of a criminal case

First of all, your behavior must belong to excessive defense. Why do you say that? Because saving people and being chased are two different behaviors, and the concept of justifiable defense refers to the defensive behavior carried out in order to avoid being infringed, and Sun's so-called defensive behavior only happened after saving people, although there is a certain causal relationship between them; Secondly, as someone upstairs said, if you are committing violent crimes such as murder, robbery, rape and kidnapping that seriously endanger personal safety and take defensive actions, causing unlawful infringement of human casualties, it is not excessive defense and will not bear criminal responsibility. In fact, Sun does not necessarily or necessarily have the above situation when defending. In fact, Sun was armed and eventually died. Third, because of the causal relationship between the two events, the judge may give a lighter or mitigated punishment when sentencing.
