If you stab someone in self-defense, the legal consequences will depend on a number of factors. These include the severity of the victim's injuries, whether the victim was armed, and whether you had a reasonable belief that you were in danger of serious bodily harm. In some cases, self-defense can be used as a justification for using deadly force, but this is not always the case. If you are facing charges for stabbing someone, it is important to speak with an experienced criminal defense attorney who can help you navigate the legal process.
