What you've said here is a prime example for why I stated earlier "no one can understand an addict except an addict". It doesn't make sense to anyone, even to ourselves. We do things we would have never even considered possible when the battle of the addicition is being waged. Its a mental illness; a brain disorder regardless of how the person first became addicted. Once that person is addicted, the disease never leaves you.
Think of it as getting meningitis or something if you must. No one really cares how you got the meningitis, just that you now have it. No one says "well, that poor sod shouldn't have been in a place where there was a disease! Screw him!"
Addiction should be looked at and dealt with in the same way as any other disease.
