Dear autor, please read my opinion

Dear autor
I perfectly understand that it's your novel(composition).
But! I have a questions.
Why did you make such an irresponsible person? In my opinion changes suddenly and a lot. People never acts like him. For example: he could make friendship(even sex-friendship) just to let them live (give them chance to do something).
the main character sometimes act like regular person/ sometimes like IDEOT/ sometimes running away from problem.
I love your navels. And yas it's my personal opinion. I wish you'll take my comment into account. I wish all the best.
