If someone is convicted of chopping people with a knife, the court will decide the corresponding punishment according to the relevant laws and regulations, such as criminal detention, fixed-term imprisonment or life imprisonment. But as a victim, you may still be able to apply to the court for criminal incidental civil compensation and seek economic compensation. However, in criminal cases, the amount and method of civil compensation are usually judged according to the defendant's economic ability and the victim's loss.
If you don't get compensation or have doubts about the court decision, you can consult your local lawyer to learn more about the relevant legal procedures and possible compensation methods. Please note that the laws and regulations vary from region to region, and the above answers are for general reference only.
