It's a challenge coin, not 30 pieces of silver, and you shouldn't hate on Judas just because of what they've told you.
Don't forget, Jesus told Judas to do it quickly, and Jesus handed His life over by His own authority. No one took it from Him.
Jesus never told you to reject any of the 12, and He told you if you love only those who love you what credit is it to you? Whatever you do to the least of these you do to Him. If you reject them, you reject Him.
Peter would deny Him three times.
