Choices of life - Abilities or other qualities

Hi,

I am wondering if JKR is trying at some level to show that: the 
reasons behind the choices we make are responsible for our character 
and the choices themselves are responsible for what we face.

Take the Marauders. It is very difficult for me to understand how 
Sirius, James and Lupin did not understand Peter a bit even after 
years of being with him. Similary, don't Sirius and Lupin know each 
other well?

I guess the Marauders became friends based on their respect for 
ability and not because they "liked" them. Draco and other make 
friends (if they have anybody to be called "true" friends) based on 
purity of blood.

Harry, on the other hand, refuses Malfoy's offer of friendship, 
instinctively and makes friends with Ron, Hermione and Hagrid.

Is this one of the lessons in the books or is it just me reading 
something into nothing?
