If someone changed their last name to “Newman,” “Forrester,” or “Carrington” because they hate their father and his last name and just liked those instead, and legally changed it, how would you feel?

I’d feel like, “Man, what did their father do? It must have been something really awful. I hope they feel better now”. But I’d also feel a bit sorry for them because I’m doubtful simply changing their name would fix whatever damage was done.
