Sforno on Genesis 3:22/ספורנו על בראשית ג׳:כ״ב

1כאחד ממנו לדעת טוב ורע, he will know good and evil even while continuing to wear “our image.” This would be an intolerable situation, as in spite of his tendency to give in to his evil urge he would live on forever. [the author considers בצלמנו as a reference to the infinite life prevailing among the celestial beings. Ed.] In such circumstances, this Adam whose evil urge was active would continue to chase the material blessings of this world, something which would prevent him from reaching the spiritual aims set for him on earth when G’d made him in the divine image.
