Dietrich Bonhoeffer shares a nugget of wisdom in his Papers and Letters from Prison. The proper way to view other human beings is through a particular lens colored by humility, self-awareness and compassion. See what he has to see about the matter.
The man who despises another will never be able to make anything of him. Nothing that we despise in the other man is entirely absent from ourselves. Why have we hitherto thought so intemperately about man and his frailty and temptability? We must learn to regard people less in the light of what they do or omit to do, and more in the light of what they suffer. The only profitable relationship to others — and especially to our weaker brethren — is one of love, and that means the will to hold fellowship with them. God himself did not despise humanity, but became man for men’s sake.
