Those who are smarter than Shlomo Hamelech who said “Hanoch le-naar al pi darco” are a big cause of boys going in improper ways.
Most boys are not future Roshei Yeshivos.
If the wrong boy is pushed in the “Rosh Yeshiva” path, he will drag the “Crown of Torah” through the mud in a public thoroughfare.
Others will be pushed away by a teacher who misrepresents a Chassidic Minhag as a a major Biblical law.
