You do not have a _right_ to kill anybody ever. However, you do have a _right to defend yourself_, within reason. That could in some situations mean that you take actions that kill someone. A judge and/or jury will decide whether it was reasonable. If it wasn't, you broke the law. They did not "take away your right" to kill.
FYI most of the world do not allow you to kill someone to defend your property. That is a very American thing. If someone takes your stuff, you call the police.
