Why was Okonkwo isolated?

Okonkwo was isolated because he was such a great man, and could not relate to others very well. His manliness outshone all others. He demanded extremely high standards, particularly when it came to his sons manhood, such that they would not be able to ever meet them. He was inflexible, stubborn, and discompassionate. He threatened those close to him when they displeased him, the most notorious incident being that of beating his wife, then discharging his gun at her all because he was annoyed at not being able to work.
