Does 'free' will exist in its complete sense?

Although the title seems to be philosophical, i am trying to see the big picture of your thought process. Over the course of evolution and towards the sole purpose of survival, human brain has attached certain significance or emotion to living or non-living things based on logical or illogical reasons. Repetitive occurrence of similar set of neurological sequence of events in human brain over ages might have given birth to so called morals.( I am not sure if morals is the right word to use). Lets for a moment accept our brain has something like a set of morals. Now, i think 'likes' or 'dislikes'; 'good ' or 'bad' involves a deciding process based on these morals. I think there is an event in the brain which involves comparison with the morals before we come to a conclusion whether it is likable or not.

I think being consistent with this process of decision making is considered as 'normal' behavior.

Now if i am not wrong, you trying to understand, what makes people to inconsistent to what is generally considered to be normal?. What might be happening in the brain? Is the part of the brain regarding morals being conquered by something else?

Rajat, make it more scientific..keep it going
