Everyone throughout the history of the world has, at some point, sought to fulfill their their own evil desires (Rom. 3:9-18; James 1:14-15). Doing this has meant they (and we) are not perfect.
Jesus, on the other hand, has always sought to do his Father’s will instead of his own (as he said in John 5:30: ‘…I seek not my own will but the will of him who sent me’): because God’s will is perfect (Rom. 12:2), Jesus was perfect because he did his Father’s will.
