your first point is interesting. you have a matrix; columns: intruder means serious harm/death, intruder does not mean harm, rows: you shoot him, you dont shoot him. In the first column you have a bad result or a really bad result. in the second column you have an awful result or a good result. In my opinion the second column is better to be in.
