Anyone who would set fire to a live dog that is calm enough to allow itself to be tied to a tree is clearly a sociopath and a threat to any other creature unable to defend itself. I can tell you that I will offer a serious beating to anyone persisting in such behavior after being asked to stop. I have to answer to the eyes in the mirror every morning and find myself unable to allow such behavior to go unchallenged. Specific actions will be decided by the escalation or de-escalation of this scenario.
Violence unchallenged is violence unleashed.
