Perhaps Samuel determined not to repeat Eli's mistakes, focused too much on the negatives involved, and ended up with sons as useless to God as Eli's. Were this not so, they would have trusted God to provide the next judge. But they had had enough of God and His system. Youth is a time of idealism. Whatever you do, you intend to do right.
Youth is accutely aware of the mistakes, failures, and shortcomings of others.
Youth determines to learn from the mistakes of others and never ever repeat them. This often makes youth a time of criticism and intolerance. This kind of improperly focused idealism leads to failure. One generation is destined to repeat and magnify the mistakes of the preceding generation if that is their focus and fixation. Young person, don't specialize in the errors of others in a judgmental way.
