Based on the given context, craft a common-sense question, especially those that are LONG, INTERESTING, and COMPLEX. The goal is to write questions that are easy for humans and hard for AI machines! To create such questions, here are some suggestions: A. What may (or may not) be the plausible reason for an event? B. What may (or may not) happen before (or after, or during) an event? C. What may (or may not) be a plausible fact about someone (or something)? D. What may (or may not) happen if an event happens (or did not happen)? You can also create other types of questions. DO NOT make your question answerable without looking at the context, or question of which the correct answer can be directly extracted from the context. DO NOT ask a question that requires very specialized knowledge that is not common sense. DO NOT ask too simple or too short questions. Your question must be related to the context and answerable with common sense. Try to add more variations and complexity to the questions.

Context: I can only pray that the chemo my father has had to undergo has made him sterile . No more kids should have to deal with his drunken abuse . As for Gina , I feel bad for her , even though she was the reason for my parents divorce ( which I thank her for ) . Her punishment for home wrecking is having to deal with my fucker father for the rest of her sad , miserable life .
Why did my father abuse his kids ?

Context: Dad , Brother , and Sister went about 20 years ago , but I did not for many reasons . One of them a big reason , which no one seems to remember but me . I may talk about that another time .
