Look, as much as I detest RYR, let's wait for all the facts before jumping to conclusions. There is a difference between an engine severe damage, and engine limit/surge/stall situation.
Also, the main difference here is probably what we don't know -HOW and WHY did the crew divert to Girona. If it was 'let's go to Girona because they've got maintenance facilities' then they probably got it wrong. If however, they spent genuine time generating options and then deciding on the best course of action, then well done.
Unthinkingly diverting back to the airfield you came from is frowned upon these days, unless your arse is on fire. Generate OPTIONS - ask open questions of the co-pilot - 'where do you think the nearest suitable airport is'? 'Give me 3 options for what we do now?' Then have an open discussion about the merits of each of the 3 airfields. Perhaps you've discussed some of this in the pre-departure brief already? As someone said,
Was the aircraft overweight for landing?
What is the priority, how much time do you have? - land asap or manage the emergency, generate options, brief the crew?
Was there debris on the runway?
You've just had multiple bird strikes, do you want to go back for some more bird strikes on one engine?
What's the weather like? Is it a difficult non precision approach at night on one engine?
Is there a big runway with an ILS that you can reach in the time you need to brief a return? Are you more familiar with that airport?
Then DECIDE and do it.
