Always easy to judge another after the fact for what they may have done wrong rather than to have engaged for perspective along the way. What has been criticized may become obvious later, but was largely unknown as events were unfolding. There is no benefit from a withdrawn critique other than to benefit one’s own ego.
Be cautious to think from the perspective of another before you would offer your insight. Focus to the benefit of improvement for another and for yourself if you are to evaluate the actions of another later on. Any evaluation will be better received if you were trusted enough to be asked to provide it.
Anyone can be a critic. Think to be more of a trusted adviser, mentor or coach that has been sought ought for their insight before you would speak of another’s past.
“Critics are men who watch a battle from a high place and then come down and shoot the survivors.” — Ernest Hemingway —
