Jesus said (John 10:10) “I came that they may have life, and have it abundantly.”  As Christians, our mission is to carry on with Jesus’ work in our world.  If sending someone back to their country of origin is likely to shorten their lives, or make their life more miserable, then ‘sending them back’ is contrary to the ethic of life as first proclaimed by Jesus, and carried on in his world by His Church.  To reduce the ‘abundance’ of a person’s life is to betray the mission of Jesus.  Making life more difficult for children, which is precisely what killing DACA does, is never acceptable for disciples of Jesus.  Jesuit universities are already defending DACA students, and ought to follow their lead.  “If any of you put a stumbling block before one of these little ones who believe in me, it would be better for you if a great millstone were fastened around your neck and you were drowned in the depth of the sea.”
