“Revenge” requires capital punishment, NEVER “Justice”.
Life, in ALL ITS FORMS, is a precious gift from G_d. Who lives and who dies is for G_d, never for governments.
To “Forgive” is also for G_d, NEVER for victims of heinous crimes. Let the animals loose in a fenced yard. Give very sharp axes, acetylene torches and nail guns to those affected by the animals actions, let NATURE take its course.
Governments should NEVER have the power of life & death. Over 1 million innocent lives are vacuumed out every year in the US because of government. We’ve seen that and other atrocities played out many times in our bloody history.
OTOH, if interested citizens wish to mete out just rewards for anti-social behavior, who am I to interfere?
Unfortunately, when government refuses to execute a murderer, they usually instead place the murderer in protective custody (”prison”) where the victim’s family members cannot get to that murderer and administer justice themselves. For them, there is no closure.
