Not acceptable #5: Animals are a good stand-in for wrestlers
A good compromise for pro wrestling organizations looking to add in the drama that the element of death brings is to use animals for the actual deaths.
Back in the WWE's classic era, there was once an angle where Jake "the Snake" Robert's beloved python Damien was 'crushed' to death by Earthquake. Tied up in the ropes, Jake had to watch while his bagged snake was squished beneath the hairy derriere of the former Sumo wrestler.

This led to Jake the Snake seeking revenge and introducing an even bigger snake named Lucifer. A similar angle involved Al Snow, who had begun taking a pet dog named Pepper to the ring with him. Big Boss Man kidnapped Pepper as part of the angle and later invited Al Snow to come to his hotel room so the dog could be returned. Boss Man fed Al Snow a roast, which turned out to be the missing dog.
Using animals somewhat removes the truly tragic element from the angle, and is in much better taste than killing off a wrestler's character.
