why did candy feel that it never seemed right about curlys fighting

Check out the quote,

Candy explains, "S'pose Curley jumps a big guy an' licks him. Ever'body says what a game guy Curley is. And s'pose he does the same thing and gets licked. Then ever'body says the big guy oughtta pick on somebody his own size, and maybe they gang up on the big guy. Never did seem right to me. Seem like Curley ain't givin' nobody a chance"
