why is is it significant that tom robinson is right-handed and doesnt have the use of his left hand ?

Atticus points out that Tom Robinson can't use his left hand, "I can't use my left hand at all. I got it caught in a cotton gin when I was twelve years old. All my muscles were tore loose." Tom could not have held Mayella down and done the damage on her with one hand.

Your so ugly when you popped out the doctor said aww what a treasure and your mom said yeah lets bury it. You're gonna get BURIED BABY BURIED BURIED BURIED BURIED XD HA-HA-HA-HA-HA-HA-HA.
