@Valve Dude has influence but he is still just a local influence so he can't just do shit like bring 20 people with him to a public tournament and have them fight his opponents, that's not how scheming works and it would reach a highter authority really quickly, which would end up badly, without even speaking about public opinion (which is especialy important when a random can have the power of an army, it's kinda dangerous to be seen as evil by normal people in that case)
Also for the 4 year thing, she was stronger than him and had her family as support, he was highter ranking but it still took a while to bring all of her support down (4 years is actualy too short for that kind of stuff, IRL it sometime took like a decade just to bring a family to it's knee unless you were like the king).
She couldn't beat him before because he stacked the deck for 4 years before trying to fight her again, the first time they fought, she kicked his ass, she is clearly stronger when he can't stack the deck in his favor (like here, if it wasn't for the enchantement, special sword and all that shit, he had no hope of winning despite training for 4 years with special stuff)
Yes, you have to beat someone before raping them, raping someone you can't overpower is kinda freaking hard, it's not a question of okay or not.
