you gotta find a way to explain the parts that don't make sense when youre making a claim that contradicts itself

The only instance in the bible where "Satan" does anything of note is in Job when he tortures Job (with the permission of God). So if bad things happen it's because God told Satan he could do it so it was part of God's plan/God's fault.

That, or the person saying that it's Satan's fault is unknowingly acknowledging that Satan is more powerful than God. They get flustered when you point this out.

if you have to thank him for the blessings, you have to blame god for the bad too. god's will right?

I think you will enjoy this link. People are afraid of death and will use any excuse to justify what happens in life, to gain favor with their god.

The god concept doesn't allow God to do evil things. When God condones things like slavery, rape and mass genocide, the slavery it turns out is gentle slavery, kind and loving. The rape is gentle and kind and consenting rape and the mass genocide is because the people were just deserving of it and it's a good thing. It blows my mind how people can allow their beliefs to override their humanity and sense of justice.
