Luke reached Anakin in the end, over twenty years later. He was able to reach where Obi-wan was not, but the time and deaths and suffering between those two points... It is easier for us to be objective and weigh by those means.
Most texts carry the bias of their author, and useful those the books were, that influence is difficult, if not impossible, to rule out. This world and worlds like it are treated similarly elsewhere. But the memories of those fond of our 'stories' are not the most objective sources. In this, you have the advantage.
