After an intense argument we had, I handily beat Jane to death.
You did what? Are you a murderer?
In a way. I had to do it.
Unless that argument involved her trying to kill you first, it doesn't justify killing someone. If people argue with you, then either argue back or ignore them.
I do not care about Jane. What I am upset about is that the prosecution called me crazy.
Well I believe you have to live with the consequences that you bring forth. You murdered someone and can't bring them back, which is very disturbing. I hope you can think hard about yourself in prison, and try to reform yourself when you get out.
