Just think about this in the simplest of terms.
If you would have shot this obnoxious drunk, you deserve to go to jail. Guns are the last option to use, not the first, just because you were armed. Imagine if every police officer that encountered a drunk choose to shoot them instead of using physical force to over come the resistance to arrest? The streets would be littered with dead drunks. Your situation does not even begin to come close to using deadly force as a healthy male. If the drunk would have kicked down the door to the rooom, you were a female and he was yelling he was going to kill you, and had a weapon to do so, he could be shot. Anything less than that and you are treading on legal thin ice,depending on the county the incident would occur. Having a open motel door is a invitation to trouble and the prosecution could have inferred you let him in to settle the matter,or engage in some other illegal activity, a bad thing.
You had many options, that you did not think about. Retreat, hand fight, use other less than lethal force options, like biting kicking,screaming for help, eye poke, groin kick, throwing objects close at hand etc. The list goes on. Facing off with a drunk is not a license to kill, you need to really think this out much better than you did.
