In other words, not even understanding the own yet in a time where
humans destroy so much because of emotions you want to build another
being while maybe some natural ones of your kind die because they do
not have enough momey, and give that artificial mind artificial
emotions.

I hope this is some joke.

We mammals tend to have own I areas in the limbic system, so already
by reducing that to just some mammilian brain you are removing
yourself out of the brain, and I did not even get who is supposed to
initiate the reasoning for the front, the sequencer or what, nor the
bit about the occipital cortex and reasoning?

Or do you mean the brain not of a mammal but some different limbic
system without the own I areas and without parts of the amygdala, as
there are programs older than mammal in there?

Maybe start with which fear(s) to do with which region(s) you are
meaning.

I don't know. My ancestors long before mammal.

Personified evolution might have thought it practical for steering
behaviours needed for own and off-springs' surviving.

Try sex without any emotions, or running away from a dangerous being
intending to kill you, afterwards you might understand more. 
... Could you name some animals non - emotional?
BTW, if I feel hungry, is that an emotion or not for you?
