Why does the hero path always have more content than the villain path?

Is this gut feeling I've always had about who I am and what I'm meant to do valid? Or is it delusional? It feels stronger than ever lately no matter how much I try to shake it

Why does the hero questline always have more content and rewards than the villain questline?

Ground battles is just decided upon whoever rats the most and knows like an autist where to shoot for a one shot. I'll never understand why retards spend thousands of hours playing this garbage.
