Hate when people call Roger a sadist, but then excuse Jack as if he didn't beat a child, (Wilfred), just because he was angry, or throw a fully sharpened spear at Ralph that thankfully "only" tore off the skin on his ribs. (and more tbh. punching piggy in the stomach.)
Roger admired Jack, and his actions in the later chapters were definitely influenced by him, intentionally or not, I stand by that.
can't write an entire roger analysis at the moment, but it's in my head I tell you
