Must a son apologize to his parents after saying to his father, "Why don't you stab me with a knife?" or to his mother, "I will stab myself with a knife," while leaving the house without permission, and is he permitted not to apologize if he fears further problems?

Disputing with one's father is an act of disobedience (uquq) that necessitates repentance. Apologizing to the father is part of this repentance. It is obligatory to appease the father and apologize to him using the best approach and at the appropriate time. If he does not accept the apology, one can involve some close individuals as mediators, while demonstrating love, obedience, and kindness towards him until his anger subsides.
