Well . . . if it is your son or daughter who is the opioid addict > this might effect what you consider to be moral.
This is not only about the person hopefully being helped, but the family members and friends and church members who so care about the addicted person.
And who has the better chance of living, in spite of one's problem? > the addict or the child who is short on food? I think this might also have somewhat to do with it.
And we need to not be like the Pharisee (Luke 18:9-14) at the front of the church looking down on the disgusting sinner at the back of the church. Or else, we are letting the evil of drug addiction feed our addiction to self-righteous conceit, perhaps.
"He can have compassion on those who are ignorant and going astray, since he himself is also subject to weakness." (Hebrews 5:2)
Love
"hopes all things" (in 1 Corinthians 13:7). And Jesus on the cross suffered and died like He did, with hope for any evil person, at all. So, we are wise to have hope for any evil person, of how God is able . . . easily able.
Someone could argue, though, at a moral level, "But it's the addict's own fault, and may be those family members were at fault for not bringing the addict up right. So, now if the child dies they are reaping what they started. But a poor child is hungry by no fault of his or her own."
"But are you ok with culling the population, by letting the addicts die?"
"And then, if we try to rescue all the addicts, what money will be left for public education and medical treatment including for people who can't help being sick and disabled . . . and what about funds for veterans after they have made their sacrifices?"
"Some addicts are hooked because of how they have been traumatized while sacrificing all they have for our country. So, why would you abandon them now?"
"Peer pressure now might lean more to pushing people to drugs, than to nicotine. If you yourself had been brought up during this culture, could you now be hooked on drugs instead of nicotine? What about nicotine addicts, then? Should we also stop treating people whose medical problems are because of nicotine abuse????"
"And what about food abusers? Should we stop treating people who are costing so much for medical conditions resulting from food abuse?"
"We all have sinned; it could have been you who gave in to your weakness in a different way than you have. Would you want God to have mercy on you?"
We all have been qualified for the welfare of God's mercy
