Mirror neurons

Oh! My dictionary has become food for ants.  Did they enter the bookbinding to learn some new words and mock at me?

I literally had to struggle to kick them out of my book. So many were killed during the process though not cautiously. I was a little bit worried on seeing them losing their lives. But did I have any other options to save my dictionary?

Seems my mirror neurons (The neurons which fires your empathy and allows you to grasp the emotions of others) are activated a little bit. But still am I really guilty for what I did? I can’t kill an animal or a bird. (Not because of my goodness but to save myself from the guilty feeling) If my mirror neurons are working then, why not fully in the case of these poor ants? If I could hear them crying, maybe I wouldn’t have.. Is it like that..? I donno actually.

An afterthought: Actually why do we need to have this weird phenomenon of empathy causing all these confusions? Actually is it really empathy or selfishness as I posted in Painful..
