A person on another forum was mean to me!

[Epimethean]

Just so, Pad, and Shell pointed this out in another example above. If someone threatens you or your family with serious injury, you do have the justified right to end his life if that is what it takes to neutralize the threat. Certainly, the police and the courts will have to determine whether you were justified in your actions, but they do so (as in this case) every day. Suggesting that people in the absolute heat of the moment are not justified in protecting the lives and well-being of themselves or their family is missing the forest for the trees.
