Is a good deed any less good if it was done with less-than-noble intentions?
Maybe so. But the Ponzi scheme guidelines don't care about motive -- they care about money. And Jason Snelling, in the end, only stole $5.3 million, returning the other $3.6 million to his investors in order to lure them into "investing" more money into his Ponzi scheme.
The district court declined to credit Snelling for the returned funds, but the Sixth Circuit reversed the sentence as procedurally unreasonable.
