In Alabama there are plenty of times you can use deadly force when you're not in fear of your life. To cite one example, part of the Alabama code regarding deadly force reads:
"(4) In the process of unlawfully and forcefully entering, or has unlawfully and forcefully entered, a dwelling, residence, or occupied vehicle, or federally licensed nuclear power facility, or is in the process of sabotaging or attempting to sabotage a federally licensed nuclear power facility,...................."
So, in theory, you could shoot someone cutting the lock of a nuclear power facility, but you had better be darned sure it isn't the night watchman who just forget his keys. And you had better be sure it is "federally licensed" as opposed to a DIY nuclear power facility built by the guy down the street.
The code goes on to discuss the defense of others including examples of forced oral sex, so if your neighbor's girlfriend doesn't like giving your neighbor the particular kind of sexual pleasure he prefers and he forces her to do so at your back yard pool party, then Alabama says "open fire".
Of course, that might not be the end of the story, but you get the point. Fear of your life is not the only instance when you can use deadly force. However, it may not be worth the effort.
Me? If someone is killing you with a baseball bat in the Walmart parking lot because of a dispute over the handicapped parking place, the best you're gonna' get from me is a phone call to 911. I will NOT shoot the guy with the bat even if the Alabama law says it might be OK.
