- Would you blame an individual who becomes addicted to gambling because it is wired to his DNA?
yes, I mean, just because it can be passed down through genes does not mean you would become a gambling addict. becoming addicted to gambling(or to anything) would most likely take time even if you have a higher chance of becoming addicted because of your gene.
-Can their gambling problem be put in check by regular methods?
pretty sure it can. I don't really see any reason why it wouldn't work for them.
-Will the addiction be worse than someone who picked up the habit?
I don't know.
