If you are not there to answer their questions, they will answer it themselves which you might not like.
The Ksav Sofer explains that בעבור זה is used both for the sheina yodea lishol and the rasha. He says, be careful when he is young when he is not asking, not knowing when to ask, answering by themselves for not being listened to, in order that they should not become a rasha.
