Please reference the post(s) or article(s) that includes the claim, "it wasn't him, it was the drugs" .. I missed that.
I still contend that TG's "choices and actions" did NOT "lead to her child's murder." TG's inviting JJR to staying with the family until he got on his feet was not so different than the Wrights inviting GG to dinner. Yes, GG has no record of pedophilia but neither does JJR (as far as we know).
Clearly, JJR had it in him to abduct, molest (assumed) and murder a child. That makes him a pedophile, which is an entirely different diagnosis than "he is addicted to drugs" (which we may confidently assume he is, as revealed by his stint in rehab <assumed drug rehab>).
If the murdering of this child was a method for him to ultimately obtaining a drug fix then I might agree with that assessment. As it stands, it appears he may have molested the child (body found with no underwear / shorts) and murdered the child.
And JJR's other issues are not directly indicative of him being a pedophile although they should have given TG pause to allowing him near her children. TG's "choice" of allowing JJR near her children no more caused JJR to murder her child than the word "day" did because it includes the letter "y".
If TG somehow knew JJR to be a pedophile, then I would totally and completely agree with the assessment.
