What a pathetic person.
One of the commonalities found in the histories of many mass murderers and sociopathic torture killers is that they also (usually as children) tortured animals.
Show me someone who inflicts pain on a helpless (and that wolf was, after capture) animal and I’ll show you a sick person who needs to be watched closely. All of us have hunted, even if only with a BB gun; and some of us have killed things we hated, such as raccoons who tore up chickens or pets, but anything other than a quick, clean kill should be reserved for Hamas or domestic terrorists, not an animal just doing what it is evolved/created to do.
