If everything has a purpose then evil doesn't exist

[Mister Agenda]

Ths same punishment for all crimes sounds like essence of injustice.

and if sin is less of a crime and more of a Spiritual infection or virus? Does a doctor always prescribe different medicine for the same disease or infection? Just because you may have different symptoms or different severity of symptoms doesn't always mean you have a different virus or infection.

The same is true for spiritual infection of sin. Just because your symptoms of the spiritual sin infection we all have are different, it doesn't mean the treatment should be different (what is needed to over come this spiritual infection) Nor does it mean that if we don't get treated it will keep us from death. As the end result of a fully developed sin infection is death.

So sin is a virus God cannot defeat unless we go through some kind of rigamarole? I get why a human doctor would need me to agree to take a vaccine, but I don't get why such a consideration would apply to an omnipotent being.
