Anyone else feels pissed after seeing Silent Sevenstars credit hogging Rudeus?

Like I get that Rudeus willingly did so. It still makes me kinda angry seeing Rudy in future historian's FraudRadar. Why doesn't Rudeus care about legacy? It's what you pass down to your children, and your children's children. It's what remains of you when you're gone. What is a human's life but a legacy?
