- if your wife becomes so mentally ill and then kills your children, make sure you quickly inform the police and don't kill her under any circumstances as otherwise you will be punished, suffer consequences and possibly a lobotomy, you will not be pardoned and treated as a good guy driven by circumstances, and not just because she is a woman etc etc etc.
Something like that, right?
The right thing to do would have been something like this:
1) Apprehend your wife, tell her she's under arrest, cuff her, tie her, maybe sedate her if possible.
2) Call the authorities, tell what happened.
3) Watch justice take place.
4) Feel no guilt about what YOU did, no matter how much you grief for the people that the psychotic hag set free in a cruel way - those 'children' are now just regular adults living a good life in the astral side, and will probably soon incarnate again to some other family, nothing is really lost per se.
5) Meditate and possibly meet those 'children' entities in your dreams, where they can tell you they are fine, everything is OK and after your body dies, you can all meet in the most happy way.
6) Realize what burden wife (even if not more psychotic than casually accepted in this world usually) and kids would be, and how much more free you are as a single guy that can now do whatever he wants in his life, how much more money you will now have, how much more time for your self and hobbies you now have, how much more you can create, achieve and accomplish in life, and how much more sex you can now have (whether in your imagination or learning to be a PUA - after all, you have all the time in the world now)..
Also, how many choices for different jobs you now have, that you don't HAVE to work very hard to support a family, you need MUCH LESS money, so you can take easier, smaller jobs that don't pay as well, but offer more freedom and free time, and so on and so forth.
In the end, doing the _RIGHT_ thing would be WIN-WIN-WIN, but doing the WRONG thing (murder is always wrong, regardless of what the 'legal system' says about it - murder is UNLAWFUL, not just illegal (there are 'legal' murders, but never, EVER a 'lawful murder').
The moral is, don't murder, let the authorities handle a psycho. ALL problems solved. Anything that happens to you after you decide to push that trigger is your own damn fault,you SHOULD be lobotomized!
