How Junior’s dad,Mr.P or his sister impact to his life ?

This is a pretty detailed question for this short space. I can comment on each of them one at a time.

Junior's dad may have been an alcoholic but he loved Junior. For all his dad's failings, Junior loved his dad too. Junior wanted to make his dad proud: he wanted to be a social and intellectual warrior. Junior saw the good in his dad even though his father had failed his family many times.
