I believe that noone is responsible for who they are. Noone decides to be lazy or aggressive or dumb. It just happens, determined by your genetic code and by how you are raised. As a consequence, I think you shouldn't judge people for their negative traits, but be sorry for them. And I think it is dumb and pointless to expect people to change. If they can, then it's in their character that they can, but someone who can't JUST CAN'T. Yes, I believe that some people cannot change their bad traits and therefore shouldn't be judged too hard. Of course I will avoid any aggressive person, and hate anyone who is not nice, but I know that, most of the time, the person who suffers most is them and therefore I feel sorry.
