If "Adamic life" is "cursed" and "Eternal life" is "blessed,"
how is the "taking away" of the "Adamic [cursed] life" and
replacing it with the "Eternal [blessed] life" (by the action of God)
considered "immoral" of Him?
If a murderer enters my home with the intention of killing my family, I would not hesitate to pull the trigger in order to protect my precious family.
The "murderer," in this case, would be considered "immoral" for his evil intentions, but my action in defending my family would not be considered "immoral," even though the end result of both "actions" would have resulted in someone's death.
"Death" is ultimately due to "Sin," in this cursed world, but our good God works all things together FOR GOOD to those who love Him. "Death" does not win, He does (as do those who trust in Him), because He has provided Eternal LIFE, and at great cost to Himself.
Oh, and one more thing...
People die every day, as a result (ultimately) of "Sin" (the Adamic "Sin principle" we've inherited from Adam), but our gracious God offers Eternal LIFE, by grace through faith in the Person and Finished Work of Jesus Christ.
"The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have LIFE, and that they might have it more abundantly."
- John 10:10
