I am fully persuaded that thousands of our fellow-men might profit equally by a similar course to mine; but, constitutions not being all alike, a different course of treatment may be advisable for the removal of so tormenting an affliction.
The process is very gradual, you see. At first there's the tainted stage; they know what will eventually happen to them if they go on but they say, 'Oh God, don't do it to me do it again, please, please.'
Life is not simple, and people can't be boxed into being either heroes or villains.
