Might wanna check Ky KRS chapter 503. In Ky you can use lethal force on anyone attempting to break into your house, already in your house, or trying to gain entrance to an occupied vehicle. We also have stand your ground laws, and we can use lethal force to: prevent death, serious injury, rape, kidnapping, arson, someone From trying to displace us from our property, and to stop someone from committing a felony. The law also says if we use deadly force to prevent any of these things, we cant be charged in criminal or civil courts. Some of the best defense laws in the country. You might wanna check Texas law as well. If the laws of the state you live in don't allow self defense, then your state of mind don't matter, and might possibly get you in trouble.
