LOL Gitana! We used to say that our daughter was born with a law degree because of her persistence!
I will try to say this as clearly as possible, even though I think I've been pretty clear.
In each hypothetical case you've mentioned, a human life is deliberately taken because the person thinks there is no way out. That is their perception, true or not. In each case there are mitigating circumstances that would be considered within the legal system. I would want each of these women to be treated fairly, with consideration. But I would hope that they would be helped to understand the gravity of what they have done, and receive appropriate help, in whatever way the law provides. I feel the same way about Gypsy.
The bottom line for me in this discussion is that a life has been deliberately taken and that needs to be taken very seriously, no matter how much abuse was endured. I personally do not believe that my life is more valuable than someone else's, even someone who harms me. I would never deliberately plot to kill someone to get out of a terrible situation. I will not choose that option for myself.
If someone else chooses that option to end abuse, they have chosen to defy the standards of our society. As sympathetic as I may be to their situation, for our society not to end up any more lawless than it already is, we need to maintain respect for those standards, even for sympathetic killers. I have addressed how I feel it should play out in the legal system in my first paragraph.
I've stated my opinion and beliefs, several times. I hope this clarifies where I'm coming from. I respect everyone's right to their opinion, even if I strongly disagree. I'm all done.
