murder is ok sometimes

murder is ok sometimes because its for self defence and justice. Firstly, murder is ok for self defence because every people in this world are hiring the other people to kill. its good to kill someone to protect your selfs when someone is trying to kill you if your innocent. Finally, Murder is ok sometimes for justice because  if you want to protect your family from the bad guys you should fight them even its against the law for examples "the stranger went to your house and going to harrash you and your family. its ok to protect your selves from bad guys even it cost their lives that it kills them and its an accident that you didnt do on purpose".
