This ish a myth just like how it's a myth that NS always join our boi boi to men, after all every person react differently to violence mah. Moi got see real cases of this kind of mindset actually backfired and not only the kids turn out even worst they got zero trust and love in their family too.
Like some years back moi neighborhood got a case of a 14yro son tio whack by his lao pek and for the first time the son finally cannot lun and retaliated and hoot back with a chair until his lao pek head break blood flow and tiagong the son still never stop and continue to whack with chair, end up mata come take the boi away.
Tia the 3 auntie and 6 ah mah neighbors gong ish the lao pek have been whacking the son for many years liao but this ish the first time the son actually hoot back, first time hoot back ish can hoot so jialark can show the kind of hatred the boi must have been fostering for years before that until one time volcano erupt all come out. Later also tiagong the boi never change good, after boy home come out never go back to family liao ish join gang then get into trouble go Changi squat.
