You have heard that it was said to the people long ago, Do not murder, and anyone who murders will be subject to judgment.
This is one of the ten commandments of the bible. Do not murder or kill anyone. So, therefore, whoever commits murder will be judged after they die. This confirms that there is a place called hell, where there is a real possibility that a person will be sent there for eternity. We need to be aware of the consequences of our actions here on earth.
