Eli’s weakness

I don’t know if we consistently recognize the magnitude of Eli’s personal failing. We may think that his counsel to his sons against making the people transgress was all he could do with grown sons but it’s clear that he could have and should have done more. What example would he have been seeing if he had subjected his sons to the full measure of the law for their sins? Israel would have seen that Eli would not even spare his own sons from the demands of justice.
