What is the illegal act of threatening to kill, and what will they do if they kill someone?

If you really kill someone, you should be punished as intentional homicide. As for the problem of being threatened, if it is only verbal, it is called threat and intimidation, and the police station should be punished according to the law on public security administration punishment; If a murder weapon is prepared in addition to the threat, it belongs to murder preparation, and criminal responsibility should be investigated (there are few cases of being investigated, but it is not without it). Someone was investigated for criminal responsibility the day before yesterday.
