Late stoppages are worse because of health reasons. There's absolutely no defending the gifs posted in OP, and referees should be held accountable for their actions. The fighters recieve fines ans suspensions, referees should too, because the safety of the fighters is essentially in their hands. Fighters are told to fight until the ref steps in, after all. Though it's really great that there are many gentlemen who will stop when their opponent is clearly out.
All that being said - I'll be brutally honest, and this may sound harsh. I hate early stoppages. In fact, I absolutely despise them. What if Lesnar-Carwin, Browne-Overeem, or Barry-Congo were stopped when they first went down? In hindsight that would have been really bad. My point being, you've got to give the fighter a fair chance to get back in the game. As a paying customer I'd much rather see the stoppage be a little late than a little early. Unless it's really extreme either way, I'd rather see a definite ending. I'm sure the fighters would too.
Food for thought.
Never will I ever be fake, never will I follow
