Welcome to Gaia! ::

It all depends on the law in your country. In New Zealand a man was tried and convicted of manslaughter for 8-10 years for shooting an assailent in his home who was raping his wife. Because although he was defending his family, the assailent wasn't aware of him.. - it sucks, and his lawyer obviously was a dumbass, but thats the law in NZ..
Be smart and read up on it! Then you know how to manipulate the system!

to be rude and obnoxious a dead body doesnt testify against you in court and say "i wasnt doing that" or "he started it" the thought i was given in reasonable force by my Yoshen was at that point and time did you stop them from continuing to try and hurt you yes if so did you stop when they dropped if yes then it was resonable if they are dead then it was justified if you continued after they were down then it was excessive ....... i asked him what if im not that good to stop them and they want to get up he said drop them so they can't get up and then walk away if they are dying let them think about life and their path while they deal with it but hey i dont know s**t so

If the guy is down run for it unless he has a gun you don't want to get shot or knifed in the back. If he is hurt and on the ground you should just leave if he is hurt he may just get up and go away. If he keeps trying to come after you and you feel he is a threat kill him. Some people I have talked to on Gaia say that even if they were in danger they couldnt kill I can't see how people can be like that to me it is suicide.
