I had always thought they went bad, when they made the decision to become a lawyer.
Anybody I ever see beating an animal with a framing hammer, will need more than a hammer to stop me from beating them unconscious.
People that beat animals, or kill them like this, are the WORST sort of cowardly blowhards, usually masking their cowardice in false bravado. (with a lot of impotence mixed in.)
Being unable to beat persons, in their impotent rage, they turn to defenseless animals to vent their emotions. Just once, I would like to be there when something like this happens, instead of reading about it afterwards.
