Hello crankalicious. I saw this question yesterday on an excursion. Sharing, when I have questions for or of "self" thus seeking answers, well, I lean toward spontaneity more than randomness. That said, I answer questions many times of great length here at the answer section as thought exercises, practice seeking more with less or the economy of words, and of course inspiration.
I agree very philosophical regarding this question and an exercise of more than thought offering a premise for a decision. Fight or flight comes to mind and then next is all the attachments of morality, ethics, and etc. However, once here I was a little dismayed.
The exchange of kill with murder seemed of a view with perspective a change of venue. I do not accept kill and murder as being synonymous, nor acknowledge each as so. Therefore, honestly do not know how at this moment to answer other than the primary question separate from the secondary. Thus, exploring is offered and, well . . .
An old service technique for customer satisfaction with regard to customer complaints is an acronym termed S-P-A-R.
I may have a bit and a byte of memory failure of some type. There is an acronym for those too. Acronyms are near to argots within fields of careers, study, and etc. May be a hub in there somewhere.
Any way, as a sail boat not adrift on a lazy Sunday morning, yet just allowing for natural, toes in the water, and pondering I would rather kill. Of course the thought in mind was a bear or a lion or even a bumble bee. Therefore, is a "body", yet "some" is the question next.
If it is a who, well, Dr. Seuss always answers that question for this "self" with Horton Hears a Who. With a bit of the imagination a body, too, is an organization likened to an organism. Then it may become more social-psychology rather than psychology.
The next question changes synapses firing and possibly misfiring too. "Would you rather murder . . . or die instead?" I have a challenge with understanding this question. Murder offers intent with definitions. That is kinda' intense.
The content of the context of the question is "live with guilt". Presumption may be seen as wrong doing. That lends to the definition of intent dancing with the philosophical of Ethics. Again, with context, "die instead" offers immense pondering. As a writer I would ask who, what, where, why, when, how, and how much with regard to cause while allowing intuition or insight a peek at inspiration.
