Can't blame someone else for the suffering man causes, when man does not listen or follow the teachings that would help to end that suffering (including that of the golden rule). At that point, the only person left to blame is the individuals causing the suffering (or turning a blind eye to the suffering when you could do something to alleviate it)
Okay a few things:
- "man" does not cause suffering, some people cause suffering to other people. We are all allways in a position to do something to prevent it or not. God does not. Question: Under what circumstances is it okay to allow someone to get raped? I say none.
- Much suffering is not caused by humans but germs, disease, aging, natural disasters etc. Question again is: When is it okay to watch someone drown when you can lift them out of the water with ease? God answer that question every day...
- Okay so a person follows the golden rule all her life and then at age 30 gets burned for witchcraft. God, apparently, sit on his trone and goes: "well, cant blame me, i told them the golden rule and as long as some of them dont follow it, i shouldnt do anything!"
- We blame people all the time for causing other people to suffer, infact we call them criminals and have special places to them. Obviously the reasoning which is good enough for god to is not good enough for us to just sit idle by and contemplate that since we told the victims and murderes alike what to do: "dont murder & be nice", it is not our place to intervene.
