Found this. Thought it would be good to discuss about it with reference to the Holy Bible especially, possible, impossible or inadvisable on the questions by Epicurus ?

Added [A], [B], [C] & [D] just for ease of reference.

But Christianity itself states the existence of evil and Satan. It's in the Bible!!!
You can't now say it does not then continue with the riddle like it is irrelevant.

But this riddle is not for atheists like me but theists like you who believe in the premise of good and evil. You don't turn around and answer the riddle as an atheist while claiming you are a theist. That's being hypocritical.

Who said the riddle is dumb? It's far from it, no theists can answer it and also maintain there is god.
Just because you can't answer or spin the answer, doesn't make the riddle dumb, it just makes you beliefs dumb. I am not expecting honesty from you.

It's not it doesn't make sense, it makes perfect sense if you don't believe in god but that does not mean you answer it as an atheist because atheists have an answer and I already stated  before, if only you took the trouble reading before trying to dispute it. As a theists you have no answer and you can't pretend to be an atheist just to attempt to answer it, that defeats the whole purpose when Epicurus is asking the believers. Basic logic!!!

Again another fallacy. Nobody was asking you to use the Bible to answer the question nor was the riddle based on the bible but since this is a catholic thread, you get your attributes of god and evil from the Bible. So what else can you base it on? If one were to ask the Mulsims, surely it won't be the Bible, it will be the Quran and they will have to or attempt to answer it based on the attributes of evil and God in the Quran.

We all agree that evil exists, including religions, it goes without saying and is the central premise of the riddle.

You don't know what atheism is (I am not trying to be rude), that's why you are asking the preceding questions. Why should we not believe that evil exists when its real? the same validity doesn't apply to god. Morals or what we base our morals on have nothing to do with atheism. You really think atheists have no morals or we are atheists because we like to commit evil? The opposite is most likely true. Atheism is based on knowledge and critical thinking not ignorance.

I put it to you the only difference between an atheist and a theist really is that we believe in one god less.

Hitler and the Nazi Party members were mostly Catholics (more than 90% of them), please don't attempt to conflate all evils on atheism. Your former Pope; Pope Benedict XVI (Ratzinger) was a Nazi party member!!!

Answering your questions

Where do you based your moral from?
My morals unlike a theist is subjective and mine is based mostly one a single moral code - The Golden Rule: "do ut des" or it is stated in the Bible as such:  Do to others as you would have them do to you  - Luke 6:31

Is it based on the current government laws?
No.

Do they hold the highest moral standard?
Atheists? Ofcourse not, there have been several atheist mass murderers in history but these people didn't base their killings on atheism unlike religious killings.

As you know each country has their own laws. Which of the country in this world has the highest moral standard?
Surveys have shown less crime is commited in countries which are less religious. So the inference here is less religion - more higher morals, there is no other explanation.

Do we based our moral on their standard? What about Hitler's government called Nazi? Are their laws evil or good? Can you define what is evil from the book of Atheism?
Answered above.

No atheism is out of scope on moral values, thats why you should know what an atheist clearly is. I try to follow the golden rule not all atheist are moral or have moral principles but most tend to have.
NO, If someone hurts me, I will try to get even, for me and for others and I am not going to be turning the other cheek. But that doesn't mean I go and harm others first or disproportionately. That would make me immoral by my own code: do ut des

No one is ever good or evil.  Good and evil is intertwined in all of us but the more we follow moral codes, the more our better side comes to play.

Pls check what atheism is, its actually very simple.

EDIT:

atheism
ˈeɪθɪɪz(ə)m/Submit
noun
noun: atheism
disbelief or lack of belief in the existence of God or gods.

It does not have anything to do with morals, how we live, what laws we follow, nothing of that sort. Only just this one :disbelief or lack of belief in the existence of God or gods. Nothing else is in the scope of atheism.

The suposed riddle is based on false premises in the first place. What is evil? To Greeks like Epicurus, perhaps infanticide is not evil.
