Revenge

Revenge, a crime of passion, sometimes... but other times it is cold and calculated. The sort of premeditation that can go into a plotted revenge can make the criminal seem more callus. When an animal combines their emotionless killing instinct with revenge, the result can be a devastating attack.

It can be hard to find the flash-point that is the catalyst for an event like this, but I did lock Kikko in the basement after he snuck down the stairs.

This isn't the case of an innocent bystander, there isn't a drop of gack outside of the shoe, every precious drop focused like a laser. With the splash pattern, it is clear that the assailant crouched to the left of the shoe, and with downward force directed the gack into the most visible location. A clear act of retribution.
