Kuldevta

So my boyf told me that Kuldevtas beat up a person if they’ve done something wrong or often times guide them through it. Narasimha Devta who is my boyfriend’s Kuldevta is known to be quite fierce. The question is suppose if Narasimha devta is not someone’s kuldevta, will they still be punished? I know I sound stupid and I’m really sorry if this post comes off as disrespectful in any way I’m just curious about all this and the culture really fascinates me. I apologise for not being able to word it out in a better way.
