While not above being vengeful and spiteful, he does as Baron Samedi commands; and the Baron is the most unpredictable, crazy and dangerous of the Guédé Loa...and the entire Vodou pantheon.
If Baron Samedi wants someone dead, then someone dies; if Baron Samedi demands you rub chilli sauce on sensitive areas, you bet Ergobé will do it. In the meantime though, in his free time, he does like to target scumbags.
