It’s an individual decision, not a collective one.
I believe our Lord, Jesus Christ when he said, “Thou shalt not kill.”
Thus, everyone falls under this parameter. (Even your aging mother in law.)
“Its an individual decision, not a collective one.”
“No man is an island.” (John Donne) Peoples’ individual decisions eventually change cultural attitudes, as evidenced by the father in Belgium who has to justify his disabled daughter’s existence, now that a decade of euthanasia has hardened the hearts of many in that country towards the old and disabled.
