What I mean is that every human being is at heart good and well meaning and if not well meaning then ultimately that person's evil is the fault of his upbringing or his genes. Every human being can be your friend in the right circumstances.
The human race as a whole is a right trashy bunch though. Constantly infighting, running towards glory and large empires only to implode a few years later, even a single nation can be horribly schizofrenic and the sum of all human actions is what we have today : a world which is inefficient, selfish and filled with misery and poverty.
Ouch that sounded pessimistic but hey
