This is dependable on the message that the paining aimed to deliver.
If the message is about promoting this form of action; then of course not only it's cringe-worthy but also inhuman and immoral. But if the message is to decline this form of behavior and teach others about the consequences of violence as well as values of family besides humanity; then that could be a useful tool.
