Kylo won many fights He beat Rey the first time he encountered her
He beat Finn
He beat POE like 5 mins into first movie
He beat multiple Royal guards from Snoke
He outsmarted Snoke
He lost to Rey the second time but was wounded by Chewie.
Kylo is easily the most interesting character left alive besides Rey.
And who cares if the general doesn't like him...the general is a joke. Snoke even beat up on the general
