If my manager told me to kill an animal I would quit first, and then report him to police and someone in the company higher up than him.
It is completely ridiculous this happened.
There really does need to be stricter punishment for animal abuse offenders. Almost all noted serial killers started their demonic ways by torturing animals. If people don't recognize animal abuse as a serious problem, then they are bound for the abusers to commit more horrendous crimes in the future.
