Lucifer
So the joke here is that this person did not know how to spell ‘Lucifer’ and instead wrote ‘Luckier’. Well, it is safe to say that nothing this person has written makes any sense, so we are choosing to ignore it. We respect all religions here as well, we hope that they change their ways and learn some respect too.
But sadly we think that there is little hope for people who say things like this. Who can actually sit there and believe the words they posted? It would take someone who is either deeply disturbed or with a mental illness to buy into such nonsense. If it was a joke, it was in poor taste.
