What can a lawyer do if he hires a lawyer for intentional homicide?

You can consult a lawyer about the case and the possible outcome, but don't order it. Lawyers are more professional than clients, so don't question it. If you are in doubt, don't hire this lawyer, or there will be a big internal problem.

Article 232 of the Criminal Law shall be sentenced to death, life imprisonment or fixed-term imprisonment of more than 10 years; If the circumstances are relatively minor, they shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years.
