Is doing an awful prank immature for a married woman with kids?

My friend pulled an ''I'm dead'' prank on her husband. She pretended to be lying on floor, bloody with stab wounds. They've been married for nearly 6 years and have 2 kids, a 4 year-old girl and a 2 year-old boy.

Obviously he's not going to leave her for that but he was upset. He thought it was real at first and nearly dialed 911. If she were just a girlfriend and no kids, that would be worth breaking up but she's a wife and mother. Are these type of pranks very immature for a married woman with kids? I personally see nothing funny about that prank. I called her out on that myself too.
