I'm not 'appealing to science', I'm using it as the yardstick that any sane system has when it comes to apportioning culpability for a crime, your bizarre objections to that notwithstanding.
AGAIN, science tells us what is, not ought.
Science cannot tell you right and wrong. We're discussing what is right and wrong.
It's like using a tape-measure to know what color the sky is.
You actually believe that an incapacity to understand one's actions should be an aggravating factor in ascertaining guilt for a crime?!
Yes. Have you noticed how many criminals use "mental illness" as a means of mitigating their punishments when otherwise their case would be open and shut?
That's not a coincidence.
So...a fully aware adult who deliberately and with malice aforethought commits first degree murder has done nothing worse than one who kills without fully realizing what they've done effectively?!!
Both have committed murder. Both are deserving death.
Man is not authorized, nor has the capability, to try to calculate the correct amount of punishment. God is and does.
There's a reason why the kind of lunacy you propose isn't accepted in both our respective countries and never will be. It fails on a scientific and just as importantly, a moral level.
I don't care what you think, Arthur.
Man is evil. God is just.
God said put the murderer, the rapist, the adulterer and the adulteress, to death.
Who are you to say we should do otherwise?
