Originally Apathy was its own deadly sin, but at some point it got jumbled into Sloth. They are connected, though not exactly the same.

The same premise definitely applies though. The Apathy don't create negative emotions, they simply remove everything. You can't attract more Grimm if you don't even care about them, or anything.
