Funny that u bring up Judas. I believe Judas was Jesus most devoted follower. Jesus put him in charge of there money and he is one of the most written about followers. Jesus said " Judas u will betray me". Most people thought it was prophecy but I personally think it was an order. Jesus knew none of the others would follow such orders. Judas did it for christ. Now the others were left in the dark about the plan so they write in bible how Judas was betrayer and how he did it for the money. I believe Judas was put in this role to show how gods plan doesn't always make sense to us and how we cant assume anything about anyone because u never know who is actually fulfilling gods will and ur just seeing it from ur own lense.
