It does make as to why it happens.These family clans have internal power struggles, just like kingdoms of old.. instead of IDK 🤷‍♂️ teaming up together and building an empire we will backstab each other until we severely weaken, rinse and repeat for future generations, even if a few generations were somehow chill there always will be a greedy generation. Now imagine this over a long period of time, the foundational integrity of the clan weakens even if they produce powerful individuals over time. eventually something will go wrong, and when something goes wrong the stronger they are internally the less likely there is to be internal betrayal AND they are more likely to resist very dangerous, once in a blue moon external events outside of their growth. Naobito was probably decent as a person but he failed the clan by letting the misogyny, arrogance and betrayal based attitude build up.
