Quoting Melissa♥:" I remember he took some of that drugs in one episode and got the club and Mexicans to believe it was ... [snip!] ... Eli's order). Eli also wanted help taking down the real IRA. But as far as I remember he never actually snitched on anything.."
He also killed one of the members! I can't think of his name. But when juice was going to get the drugs from his 'hiding spot' over in the wooded area, one of the members came up and saw him getting it and pointed a gun at him and told him he was going to go tell the club what he did, Juice ended up shooting him in the head and killing him then blaming HIM for taking the drugs.. That is certainly MORE than enough reason to kill him. But I really hope they dont!
