Without wishing to butt in or hijack SH's argument, I think what he's saying is that if one's going to blame mankind for the evil deeds resulting from free will, it's a double standard to credit God with the good deeds resulting from free will.
Agreed. I wouldn't credit God with a miraculous victory by one team/individual or another in a sporting event. I do agree with crediting Him for granting the
ability to manage such a thing ourselves, though.
Example, since some around here are having trouble understanding the difference:
If I go into my backyard and decide to move a tree stump uglyin' up the place back there...and I'm successful in doing this thing that not everyone can do...then I thank God for the drive to keep myself in good physical shape, able to go root up tree stumps by hand. I don't credit Him the decision to move the tree stump or for actually removing the thing...but I recognize I wouldn't be able to do it if not for Him. I'd be fat, lazy and weak, and a ridiculous tree stump would have victory over me. I'm very glad that's not the case, as it may be for some, so I thank Him very much for that.
Similarly, if I try to do complex algorithms in my head and fail...which is pretty much how one can expect that to go...I might well pray that God grant me, or even teach me, that ability if it were something I needed. I'd still expect to have to do the work behind that but I recognize I couldn't do it without Him.
