Ellen White specifically addresses the fact that Judas, as treasurer for the disciples, would pay himself out of the disciples’ fund for services he rendered: “Often when he did a little service for Christ, or devoted time to religious purposes, he paid himself out of this meager fund. In his own eyes these pretexts served to excuse his action; but in God's sight he was a thief” (DA 717.2). She further elaborates: “This little money was to Judas a continual temptation, and from time to time, when he did a little service for Christ, or devoted a little time to religious purposes, he paid himself out of the meager fund collected to advance the light of the gospel” (4T 42.1). And again: “He carried the purse containing the means to be used in carrying forward the work of Christ, and little sums were from time to time applied to his own use” (4T 487.2). Ellen White uses Judas’s example to warn against selfishness and misappropriation of funds in God’s work. She makes it clear that Judas was the only one among the disciples who paid himself out of the common fund, and she condemns this practice as dishonest and selfish.

Yes, Ellen White makes it clear that Judas believed himself to be above the other disciples in several ways: - "Judas had a high opinion of his own executive ability. As a financier he thought himself greatly superior to his fellow disciples, and he had led them to regard him in the same light. He had gained their confidence, and had a strong influence over them" (DA 559.3). - "If there was a highest place, Judas was determined to have it, and that place was thought to be next to Christ" (DA 644.1). - "If Judas were only received as a counselor, he thought, he could suggest many plans for the advantage of the little church. His principles and methods would differ somewhat from Christ's, but in these things he thought himself wiser than Christ" (DA 719.3). These statements show that Judas not only considered himself superior in ability and judgment, but also sought the highest position among the disciples and even believed his own methods were wiser than those of Christ.
