The Lord, in all His conflicts brought about by temptations, never fought out of self-love, that is, for Himself, but for all throughout the universe. He did not fight therefore to become the greatest in heaven, for that is contrary to Divine love. He scarcely did so to become the least. He fought solely so that all others might become something and be saved, as He Himself also declares in Mark,
The two sons of Zebedee said, Grant us to sit in Your glory, one on Your right hand and the other on Your left. Jesus said, Whoever would be great among you must be your minister, and whoever would be first among you must be slave of all. For the Son of Man also came not to be ministered to but to minister, and to give His life as the price of redemption for many. Mark 10:37, 43-45.
