This might be more of a serious answer than you were expecting, but Deconstruction kind of has a manic and evil vibe to it, and I feel like the toilet humor kind of adds to the choas in a way that fits the vibe. It fits the absurdist theme of the album lyrics as well of someone searching for the universe's answers only to find there are no answers and you have to find your own answers and meaning in face of an "infinite void of nothing". 

Whereas to me it sounds more like in Empath...Devin views himself more as an enlightened spiritual leader and actually offers his audience some "answers". I like the absurdist themes in Deconstruction over Empath where it feels like Devin has more hubris after being in the peak on his career.
