I have no strong religious identity at all but from reading the Bible, it would seem Humankind was entrusted with the Earth,with total free will to do and choose between good and bad,right and wrong.

This is a bad comparison I know but it's a 'bit' like your Parents,they go off round the World out of contact and entrust their home and land to their Family.
In the time they have that free run of things, should the family ruin or destroy elements or all of the home and land,also should they get into battles and maybe harm or even kill another family member/s , Who is to blame for that? The Parents who entrusted their property,land and all else to them in their absence or the family who carried out and allowed to be carried out the destruction and harm?

I forget who said it, (I think Oliver Cromwell may have), but in despair or conflict everyone who believes,believes God (whatever,whoever any deity may be),is on their side. It may be pertinent to ask 'God must often wonder who is on his side'.

If faith and prayer helps to console in any way then that likely is a good thing.

The Earth though is a very beautiful place,Humans have full access and full running of it, if a mess is made of that surely the only people to blame are the people who cause harm and destruction to it and to their fellow humans from their free will and choice to do so.
Nothing to do with a God who gives the total freedom to choose good or bad, right or wrong.
